Question

surface area of the sphere is 154 cm square then find the volume of the sphere

Answer 1

Let radius of sphere be r.

Surface area of sphere = 154 cm2

⇒ 4πr2 = 154 cm2



Volume of sphere =



Therefore, the volume of the sphere iscm3.

Hope this will help you.

T.S.A of sphere = 154 cm²

$4 \pi r^2 = 154$

$\pi r^2 = 154/4$

$r^2 = 154/4 * 7/22$

$r^2 = 12.25$

$r = \sqrt{12.25}$

$r = 3.5 cm$

Now lets find the volume!

$4/3 \pi r^3$

$4/3 * 22/7 * 3.5 * 3.5 * 3.5$

$= 179.6 cm^3$
