Question

Find the volume(in cm^3) of a sphere of diameter 7cm

Answer 1

SOLUTION

Given,

Diameter= 7cm

Radius= 7/2 = 3.5cm

FORMULA OF SPHERE

$= > V = \frac{4}{3} \pi {r}^{3} \\ \\ = > V = \frac{4}{3} \times \frac{22}{7} \times (3.5) {}^{ 3} \\ \\ = > V= \frac{4}{3} \times \frac{22}{7} \times 3.5 \times 3.5 \times 3.5 \\ \\ = >V= \frac{4 \times 22 \times 0.5 \times 3.5 \times 3.5}{3} \\ \\ = > V = \frac{539}{3} = 179.66cm {}^{3}$
