Question

solve it ................​

Answer 1

Hey!

C.S.A = 12320 cm^2

Radius = 56 cm

$\sf \: C.S.A = 2 \pi \: rh$

$\sf \: 12320 \: = 2 \times \dfrac{22}{7} \times 56 \times h$

$\sf \: 12320 \: = \dfrac{2464}{7} h$

$\sf \: h = \dfrac{1320 \times 7}{2464}$

$\sf \: h = \dfrac{9240}{2464}$

$\sf \: h = 3.5 \: cm$

Answer 2

Question

The C.S.A of right circular is 12320 cm ^2 if the radius of its base is 56 cm . find its height ?

Solution

What is given here ?

it is given here that

• the C.S.A is =12320 cm^2
• the radius = 56 cm

What we have to find here ?

we have to find here

• the height

How to find it ?

we can simply find it by using the formula

• C.S.A = 2πrh

Answer

according to the given question putting the value of the formula

$\bold{c.s.a} = 2 \pi \: r \: h \:$

we get ,

$12320 = 2 \times \frac{22}{7} \times 56 \times h$

now we have to find the value of h .

$= > 12320 = \frac{2464}{7} h$

$= > h = \frac{1320 \times 7}{2464}$

$= > h = \frac{9240}{2464}$

$= > \bold{h = 3.5cm}$

so we have the required answer to the given question .

• height is 3.5 CM
