Question

What is the volume of a sphere whose surface area is 154 cm

Answer 1

Hey mate....

Here is your answer...

Surface area of share = 4a^2

4a^2 =154
a^2 = 154/2

a^2 = 77

a = root 77
Now,
Volume of sphere = 2/3 pi r ^3

=2/3 * 22/7 * root 7

=22*11root7 cm^3




Hope it helps!!!!!

Answer 2

$\bold{Solution}$

Given,

Surface area of sphere =154cm

$\boxed{Surface\:area\:of}\: Sphere=4πr^2$

To find Volume=?

$\boxed{Volume=4/3πr^3}$

Radius =?

Let's begin!!

4πr^2 = 154

or, 4*22/7*r^2 = 154

or 4*r^2 = 49

or, r^2 = 49 / 4

or, r = 7/2

volume=

4/3πr^3=4/3*22/7*7/2*7/2*7/2

= 539/3cm^3

= 179.7cm^3

$\boxed{Volume=179.7cm^3}$
