If last digit of a number is 2 then unit digit of cube of the number is 8

If last digit of a number is 3 then unit digit of cube of the number is 7

If last digit of a number is 4 then unit digit of cube of the number is 4

If last digit of a number is 5 then unit digit of cube of the number is 5

If last digit of a number is 6 then unit digit of cube of the number is 6

If last digit of a number is 7 then unit digit of cube of the number is 3

If last digit of a number is 8 then unit digit of cube of the number is 2

If last digit of a number is 9 then unit digit of cube of the number is 9

the length and breadth of a rectangular Courtyard is 75 and 32 find the cost of levelling it at the rate of 3 rupees per metre also find the distance covered by a boy to take a round of the courtyard

Answer»

Answer:

LENGTH =75m

breadth=32m

:.Area= 75x32= 2400 m squared

The COST of leveling it= 3x area

2400 x 3

= 7200

therefore the cost of level the courtyard= ₹7200

the distance by the boy = 4 x perimeter

perimeter= 2( l + B)

2x( 75+32)

The equation which represents the above situation algebraically isa)2 + 7 − 120 = 0b) 2 + 5 − 120 = 0c) 82 + 7 − 120 = 0d) 2 + 2 − 120 = 0

Answer»

Given : The road from Alwah to Chagotar, is exactly perpendicular to the road going from Chagotkar to Barogh.

The distance covered by the road between Chagotkar and Barogh is 7 kilometers more that the distance of the road connecting Alwah and Chagotkar.

Ayushi is an engineer looking after the project of building a direct bypass road that would connect Alwah and Barogh and has proposed to construct a 17 km direct bypass road between the two cities.

To Find :

The equation which represents the above situation algebraically is-

a) x² + 7X − 120 = 0

b) x² + 5x − 120 = 0

c) 8x² + 7x − 120 = 0

d) x² + 2x − 120 = 0

Solution :

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the SUM of the squares of the other two perpendicular sides.

x² + (x + 7)² = 17²

=> x² + x² + 14x + 49 = 289

=> 2x² + 14x - 240 = 0

=> x² + 7x - 120 = 0

x² + 7x − 120 = 0 represents the situation algebraically

The volume of a cylindrical can is 3.08 liter. If the area of its base is 154 sq.cm. Find its curved surface area.Please answer with a picture of clear explanation.

Answer»

Answer:

$\\$

$\frak{Given}\begin{cases}\sf{Volume\:of\:Cylinder=\bf{3.08\:litre.}}\\\sf{Area\:of\:Base=\bf{154\:sq\:cm.}}\end{cases}$

$\\$

$\underline{\bf{\bigstar\:To\:Find:-}}$

$\\$

The CURVED Surface Area (CSA) .

$\\$

$\underbrace{\underline{\bf{\bigstar\:Required\:Solution:-}}}$

$\\$

» We are given with the area of base of cylinder, which is nothing else but the area of a CIRCLE, USING this we WOULD find the radius of the cylinder.

» Then, using the radius and the given volume, we would find the height of the cylinder.

» After finding the radius and height, using the formula, we would find the Curved surface Area of the cylinder.

$\\$

◐ Finding the radius of the cylinder ◑

$\\$

We have -

Area of base = 154 cm²

We know:

$\odot\;\boxed{\sf Area_{\:circle}=\pi r^2}$

So,

$\displaystyle \colon \rarr \sf \: \cancel{154 }\: {cm}^{2} = \dfrac{ \cancel{22}}{7} \times {r}^{2} \\ \\ \displaystyle\colon \sf \rarr \: 7 \times 7 \: {cm}^{2} = {r}^{2} \\ \\ \colon \rarr \sf \: r = \sqrt{7 \times 7 \: {cm}^{2} } \\ \\ \red{\colon \dashrightarrow} \boxed{ \frak{ \green{r = 7 \: cm}}}$

$\\$

◐ Finding the height of the cylinder ◑

$\\$

We have :

Radius = 7cm
Volume = 3.08 litre = 3.08×1000 cm³ = 3080 cm³

We know :

$\odot\;\boxed{\sf Volume_{\:cylinder}=\pi r^2h}$

So,

$\displaystyle \colon \rarr \sf \: \cancel{3080} \: {cm}^{ 3} = \frac{ \cancel{22}} {7} \times {(7 \: cm)}^{2} \times h \quad\\ \\ \displaystyle \colon \rarr \sf \: \cancel{ 140 }\: {cm}^{3} = \frac{1}{ \cancel7} \times \cancel7 \: cm \times \cancel7 \: cm \times h \\ \\ \colon \sf\rarr \: 20 \: \cancel {cm}^{3} = h \: \cancel {cm}^{2} \\ \\ \red{\colon \dashrightarrow} \boxed{ \frak{ \purple{h = 20 \: cm}}}$

$\\$

◐ Finding CSA of the cylinder ◑

$\\$

We have :

Radius = 7 cm
Height = 20 cm

We know :

$\odot\;\boxed{\sf CSA_{\:cylinder}=2\pi rh}$

So,

$\displaystyle\colon\rarr\sf\: CSA=2\times \dfrac{22}{\cancel7}\times\cancel7 \times 20 \:cm^2\\ \\ \sf\colon\rarr \: 2\times 22\times 20 \: cm^2\\ \\ \red{\colon\dashrightarrow}\underline{\boxed{\bf{\pink{CSA=880\:cm^2}}}}$

$\\$

$\therefore\;\underline{\sf The\:CSA\: of\:the\:cylinder=\bf{880\:cm^2.}}\\$

$\\$
