Find the volume of a right circular cylinder of a diameter of base 14 cm and height 40cm

Answer»

Given :

Diameter of BASE of CYLINDER = 14cm.
Height of Cylinder = 40cm.

To Find :

VOLUME of Cylinder.

Solution :

$\longmapsto\tt{Diameter=14cm}$

$\longmapsto\tt{Radius=\cancel\dfrac{14}{2}=7cm}$

$\longmapsto\tt{Height=40cm}$

Using Formula :

$\longmapsto\tt\boxed{Volume\:of\:Cylinder=\pi{{r}^{2}h}}$

Putting Values :

$\longmapsto\tt{\dfrac{22}{\not{7}}\times{7}\times{\not{7}}\times{40}}$

$\longmapsto\tt{22\times{7}\times{40}}$

$\longmapsto\tt\bold{6160{cm}^{3}}$

So , The volume of Cylinder is 6160cm³..

_______________________

C.S.A of Cylinder = 2πrh
T.S.A of Cylinder = 2πr(r+h)
Volume of Cylinder = πr²h

Answer» Step-by-step EXPLANATION: $\bf{\underline{\underline\red{Given:-}}}$ If TWICE the age of A is added to B's age, the sum is 45. If twice the age of B is added to A's age, the sum is 30. $\bf{\underline{\underline\blue{To\:Find:-}}}$ The age of B $\bf{\underline{\underline\green{Solution:-}}}$ Let The present age of B = x And present age of A = y According to the 1st condition:- If twice the age of A is added to B's age, the sum is 45 $\rm \implies x + 2y = 45.....(i)$ According to the 2nd condition:- If twice the age of B is added to A's age, the sum is 30. $\rm \implies 2x + y = 30.....(ii)$ Multiplying equation (i) with 2 $\rm \implies 2(x + 2y = 45)$ $\rm \implies 2x + 4y = 90.....(iii)$ Subtracting equation (ii) from (iii) $\rm \implies (2x + 4y )- (2x + y) = 90 - 30$ $\rm \implies 2x + 4y - 2x - y = 60$ $\rm \implies3y = 60$ $\rm \implies y = \dfrac{60}{3} = 20$ Substituting y = 15 in equation (i) $\rm \implies x + 2y = 45$ $\rm \implies x + 2(20) = 45$ $\rm \implies x +40 = 45$ $\rm \implies x = 45 - 5$ $\rm \implies x = 5$ $\boxed{ \rm \therefore Present \: age \: of \: B = 5years}$

. If twice the age of A is added to B's age, thesum is 45 and if twice the age of B is added toA's age, the sum is 30. Then the age of B is

Answer»

Step-by-step EXPLANATION:

$\bf{\underline{\underline\red{Given:-}}}$

If TWICE the age of A is added to B's age, the
sum is 45.

If twice the age of B is added to
A's age, the sum is 30.

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

The age of B

$\bf{\underline{\underline\green{Solution:-}}}$

Let

The present age of B = x

And present age of A = y

According to the 1st condition:-

If twice the age of A is added to B's age, the

sum is 45

$\rm \implies x + 2y = 45.....(i)$

According to the 2nd condition:-

If twice the age of B is added to A's age, the sum is 30.

$\rm \implies 2x + y = 30.....(ii)$

Multiplying equation (i) with 2

$\rm \implies 2(x + 2y = 45)$

$\rm \implies 2x + 4y = 90.....(iii)$

Subtracting equation (ii) from (iii)

$\rm \implies (2x + 4y )- (2x + y) = 90 - 30$

$\rm \implies 2x + 4y - 2x - y = 60$

$\rm \implies3y = 60$

$\rm \implies y = \dfrac{60}{3} = 20$

Substituting y = 15 in equation (i)

$\rm \implies x + 2y = 45$

$\rm \implies x + 2(20) = 45$

$\rm \implies x +40 = 45$

$\rm \implies x = 45 - 5$

$\rm \implies x = 5$

$\boxed{ \rm \therefore Present \: age \: of \: B = 5years}$

X=4-√15 find x+1/x please give answer of these

Answer»

Answer:

8

Step-by-step explanation:

R.T.P {REQUIRED to prove} : X+1/x

Given x = 4-√15

1/x = 1/4-√15

It's Rationalising factor is 4+√15

So, 1/(4-√15) x (4+√15)/(4+√15)

= (4+√15)/ [(4)^2 - (√15)^2]

=(4+√15)/16-15

= (4+√15)

(4-√15) + (4+√15)

+√15 and -√15 GETS cancelled

4+4

=8

(a) If two vertices of a parallelogram are(3, 2) and ( 1, 0) and the diagonalsintersect at (2, - 5) then find the othertwo vertices.

Answer»

Answer:

(1, - 12), (3, - 10)

Step-by-step explanation:

One of the PROPERTIES of parallelogram is "The DIAGONALS of PARALLELOGRAMS bisect each other".

The coordinates of midpoint are [( $x_{1}$ + $x_{2}$ )/2, ( $y_{1}$ + $y_{2}$ )/2]

~~~~~~~~~~

Let A (3, 2) and B (1, 0) are two vertices of a parallelogram, and O (2, -5) is the diagonals intersect.

AO = OC

$\frac{3+x}{2}$ = 2 ⇒ x = 1

$\frac{2+y}{2}$ = - 5 ⇒ y = - 12

C (1, - 12)

BO = OD

$\frac{1+x}{2}$ = 2 ⇒ x = 3

$\frac{0+y}{2}$ = - 5 ⇒ y = - 10

Answer» Answer:Your answer is (a) 937500 Step-by-step explanation: 25% of 10,00,000 + 10,00,000 ( FIRST 10 years) =25/100 × 10,00,000 + 10,00,000 = 250,000 + 10,00,000 = RS 12,50,000 Again, 25% of 12,50,000 - 12,50,000 ( Next 10 years) = 12,50,000 - 25/100 × 12,50,000 = 12,50,000 - 3,12,500= Rs 9,37,500 Please mark as the BRAINLIEST!

The price of a house increased by 25% after 10 yr,reduces by 25% during the subsequent 10 yr. If thepresent cost is 10 lakh, what will be its cost after20 yr?(a) 937500(c) 850000(b) 900000(d) 725000

Answer»

Answer:Your answer is (a) 937500

Step-by-step explanation:

25% of 10,00,000 + 10,00,000 ( FIRST 10 years)

=25/100 × 10,00,000 + 10,00,000

= 250,000 + 10,00,000

= RS 12,50,000

Again,

25% of 12,50,000 - 12,50,000 ( Next 10 years)

= 12,50,000 - 25/100 × 12,50,000

= 12,50,000 - 3,12,500= Rs 9,37,500
