Question

Find the volume of a sphere whose radius is 3cm.​

Answer 1

Answer:

Volume of the sphere (V) = 36π cm³

Explanation:

Given radius of a sphere (r) = 3cm

we know that,

Volume of a sphere = 4/3πr³

Now,

V= 4/3π x (3cm) ³

V=4 x π x 3²( cm)³

V=4 x π x 9

V=36π x cm³

Therefore,

Volume of the sphere (V) = 36π cm³

Answer 2

Step-by-step explanation:

Formula to find volume of sphere =

$\tt V= \dfrac{4}{3} \pi {r}^{3}$

Radius = 3cm

$\implies \tt V = \dfrac{4}{3} \times \dfrac{22}{7} \times 3 \times 3 \times 3 = {113.1cm}^{3}$
