4. If the volume of a right circular cone of height 9 cm is 48 T cm", find the diameter of itsbase.

Answer»

Let R be the radius of the cone.

$= > volume = \frac{1}{3}\pi \: {r}^{2} h$

$= > 48 = \frac{1}{3} \times 3.14 \times {r}^{2} \times 9$

$= > {r}^{2} = \frac{48 \times 3}{3.14 \times 9} = \frac{144}{28.26} = 5.48$

$= > r = 2.34cm$

DIAMETER = 2R = 4.68cm

Hence, diameter of the right circular cone is 4.68cm.

A rectangular grassy plot is 75 metre long and 60 metre broad. it has 2 metre wide path all around it. find the area of the path and the cost of gravelling it at rupees 3.60 per sq. m..answer is 556 sq metre rupees 200 1.60..show me the explanation.

Answer»

ANSWER:

Step-by-step EXPLANATION:

AREA of path = Area of outer rectangle - Area of grassy plot

length of plot = 75M, breadth = 60m

∴Area of plot = l * B = 75*60

= 4440m²

length of rectangle formed = 75 + 2 + 2 = 79

breadth = 60+2+2 = 64

∴Area of big rectangle = 79*64

=5056

∴Area of path = 5056 - 4440 = 616m²

∴cost of path = 3.6*616 = Rs 2217.6

Answer» Question: To solve: $\sf \dfrac{32}{x} + \dfrac{33}{y} = 31 \ \ \ \ ; \ \ \ \dfrac{33}{x} + \dfrac{32}{y} = 34$ Solution: Let the first equation be Eq(1), and let the second equation be Eq(2). $\sf \Longrightarrow \dfrac{32}{x} + \dfrac{33}{y} = 31 \ \ \dashrightarrow Eq(1)$ $\sf \Longrightarrow \dfrac{33}{x} + \dfrac{32}{y} = 34 \ \ \dashrightarrow Eq(2)$ To make solving easier, let's consider that: $\Longrightarrow \sf {\dfrac{1}{x} = a \ \ and \ \ \dfrac{1}{y} = b}$ Substitute these values in the two equations given in the question. For equation 1: $\sf \Longrightarrow \dfrac{32}{x} + \dfrac{33}{y} = 31$ $\sf \Longrightarrow 32 \times \Bigg[\dfrac{1}{x}\Bigg] + 33 \times \Bigg[\dfrac{1}{y}\Bigg] = 31$ $\sf \Longrightarrow 32 \times \Bigg[a\Bigg] + 33 \times \Bigg[b\Bigg] = 31$ $\sf \Longrightarrow 32a + 33b = 31 \ \ \dashrightarrow Eq(3)$ Let the above equation be named Eq(3). For equation 2: $\sf \Longrightarrow \dfrac{33}{x} + \dfrac{32}{y} = 34$ $\sf \Longrightarrow 33 \times \Bigg[\dfrac{1}{x}\Bigg] + 32 \times \Bigg[\dfrac{1}{y}\Bigg] = 34$ $\sf \Longrightarrow 33 \times \Bigg[a\Bigg] + 32 \times \Bigg[b\Bigg] = 34$ $\sf \Longrightarrow 33a + 32b = 34 \ \ \dashrightarrow Eq(4)$ Let the above equation be named Eq(4). On observing both the equations 3 and 4, you can tell that they're of the form; ax + by = c₁ bx + AY = c₂ When equations are of this form, we can USE the Add & Subtract Method to solve them. [Any other method is fine too, this one's quicker for these kind of questions] Adding equations (3) and (4) we get: ⇒ 32a + 33b + [33a + 32b] = 31 + [34] ⇒ 65a + 65b = 65 ⇒ 65[a + b] = 65 ⇒ a + b = 1 → Let this be Eq(5) Subtracting equations (3) and (4) we get: ⇒ 32a + 33b - [33a + 32b] = 31 - 34 ⇒ 32a + 33b - 33a - 32b = -3 ⇒ -a + b = -3 → Let this be Eq(6) Now, on adding Eq(5) and Eq(6) we get: ⇒ a + b + [-a + b] = 1 + [-3] ⇒ a + b - a + b = 1 - 3 ⇒ 2b = -2 ⇒ b = -1 Substitute the VALUE of "b" in Eq(6). ⇒ -a + b = -3 ⇒ -a + [-1] = -3 ⇒ -a - 1 = -3 ⇒ -a = -3 + 1 ⇒ -a = -2 ⇒ a = 2 Now we've got the values of both "a" and "b". Now substitute both "a" and "b" in 1/x = a and 1/y = b RESPECTIVELY, For 'x': $\Longrightarrow \sf \dfrac{1}{x} = a \\$ $\Longrightarrow \sf \dfrac{1}{x} = 2 \\$ $\Longrightarrow \boxed{\sf x = \dfrac{1}{2}}$ For 'y': $\Longrightarrow \sf \dfrac{1}{y} = b$ $\Longrightarrow \sf \dfrac{1}{y} = -1$ $\Longrightarrow \boxed{\sf y = -1}$ Therefore: x = 1/2 y = -1 Hence solved.

Question: To solve:

$\sf \dfrac{32}{x} + \dfrac{33}{y} = 31 \ \ \ \ ; \ \ \ \dfrac{33}{x} + \dfrac{32}{y} = 34$

Solution:

Let the first equation be Eq(1), and let the second equation be Eq(2).

$\sf \Longrightarrow \dfrac{32}{x} + \dfrac{33}{y} = 31 \ \ \dashrightarrow Eq(1)$

$\sf \Longrightarrow \dfrac{33}{x} + \dfrac{32}{y} = 34 \ \ \dashrightarrow Eq(2)$

To make solving easier, let's consider that:

$\Longrightarrow \sf {\dfrac{1}{x} = a \ \ and \ \ \dfrac{1}{y} = b}$

Substitute these values in the two equations given in the question.

For equation 1:

$\sf \Longrightarrow \dfrac{32}{x} + \dfrac{33}{y} = 31$

$\sf \Longrightarrow 32 \times \Bigg[\dfrac{1}{x}\Bigg] + 33 \times \Bigg[\dfrac{1}{y}\Bigg] = 31$

$\sf \Longrightarrow 32 \times \Bigg[a\Bigg] + 33 \times \Bigg[b\Bigg] = 31$

$\sf \Longrightarrow 32a + 33b = 31 \ \ \dashrightarrow Eq(3)$

Let the above equation be named Eq(3).

For equation 2:

$\sf \Longrightarrow \dfrac{33}{x} + \dfrac{32}{y} = 34$

$\sf \Longrightarrow 33 \times \Bigg[\dfrac{1}{x}\Bigg] + 32 \times \Bigg[\dfrac{1}{y}\Bigg] = 34$

$\sf \Longrightarrow 33 \times \Bigg[a\Bigg] + 32 \times \Bigg[b\Bigg] = 34$

$\sf \Longrightarrow 33a + 32b = 34 \ \ \dashrightarrow Eq(4)$

Let the above equation be named Eq(4).

On observing both the equations 3 and 4, you can tell that they're of the form;

ax + by = c₁

bx + AY = c₂

When equations are of this form, we can USE the Add & Subtract Method to solve them.

[Any other method is fine too, this one's quicker for these kind of questions]

Adding equations (3) and (4) we get:

⇒ 32a + 33b + [33a + 32b] = 31 + [34]

⇒ 65a + 65b = 65

⇒ 65[a + b] = 65

⇒ a + b = 1 → Let this be Eq(5)

Subtracting equations (3) and (4) we get:

⇒ 32a + 33b - [33a + 32b] = 31 - 34

⇒ 32a + 33b - 33a - 32b = -3

⇒ -a + b = -3 → Let this be Eq(6)

Now, on adding Eq(5) and Eq(6) we get:

⇒ a + b + [-a + b] = 1 + [-3]

⇒ a + b - a + b = 1 - 3

⇒ 2b = -2

⇒ b = -1

Substitute the VALUE of "b" in Eq(6).

⇒ -a + b = -3

⇒ -a + [-1] = -3

⇒ -a - 1 = -3

⇒ -a = -3 + 1

⇒ -a = -2

⇒ a = 2

Now we've got the values of both "a" and "b". Now substitute both "a" and "b" in 1/x = a and 1/y = b RESPECTIVELY,

For 'x':

$\Longrightarrow \sf \dfrac{1}{x} = a \\$

$\Longrightarrow \sf \dfrac{1}{x} = 2 \\$

$\Longrightarrow \boxed{\sf x = \dfrac{1}{2}}$

For 'y':

$\Longrightarrow \sf \dfrac{1}{y} = b$

$\Longrightarrow \sf \dfrac{1}{y} = -1$

$\Longrightarrow \boxed{\sf y = -1}$

Therefore:

x = 1/2

y = -1

Hence solved.

Answer» ANSWER: Draw BL⊥PQ and CM⊥RS. As PQ∥RS, so, BL∥CM. The alternate INTERIOR angles are equal, so, ∠LBC=∠MCB (1) It is known that the angle of reflection is equal to the angle of INCIDENCE, THEREFORE, ∠ABL=∠LBC (2) And, ∠MCB=∠MCD (3) From equation (1), (2) and (3), ∠ABL=∠MCD (4) Add equation (1) and (4), ∠LBC+∠ABL=∠MCB+∠MCD ∠ABC=∠BCD Since, these are the interior angles and are equal, hence, AB∥CD.

10. In Fig. 10.16, P is a point in the interior of ZRSQ. PR 1 RS and PQI QS,If RSQ = 29, find the measure of ZRPQR5SFig. 10.16

Answer»

ANSWER:

Draw BL⊥PQ and CM⊥RS. As PQ∥RS, so, BL∥CM.

The alternate INTERIOR angles are equal, so,

∠LBC=∠MCB (1)

It is known that the angle of reflection is equal to the angle of INCIDENCE, THEREFORE,

∠ABL=∠LBC (2)

And,

∠MCB=∠MCD (3)

From equation (1), (2) and (3),

∠ABL=∠MCD (4)

Add equation (1) and (4),

∠LBC+∠ABL=∠MCB+∠MCD

∠ABC=∠BCD

Since, these are the interior angles and are equal, hence, AB∥CD.
