Question

Find the volume of a sphere with a radius of five

Answer 1

Solution:

Given:

$A\text{ sphere with radius r = 5}$

The volume of a sphere is calculated using the formula below;

$V=\frac{4}{3}\pi r^3$

Substituting the value of r into the formula;

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\times\pi\times5^3 \\ V=\frac{4}{3}\times\pi\times125 \\ V=\frac{500}{3}\pi\text{ cubic units} \end{gathered}$

Therefore, the volume of the sphere is;

$V=\frac{500}{3}\pi$

The correct answer is OPTION B.
