Question

Find the volume of a sphere whose radius is $0.63m$ (Assume $\pi =22/7$).

Answer 1

Compute the volume of the sphere:

Given : Radius, $r=0.63m$

Volume of sphere $=\frac{4}{3}\pi r^3$

$$\begin{gathered} =\frac{4}{3}\pi \times {\left(0.63\right)}^3 \\ =\frac{4}{3}\times \frac{22}{7}\times 0.250047 \\ =1.0478m^3 \end{gathered}$$

Hence, the volume of the sphere is $1.0478m^3$.
