Question

I have this question about volume of spheres, can you help me out ?

Answer 1

Given:

The diameter of the sphere = 42 cm

To find the volume of the given sphere.

Formula:

The volume of a sphere is given by $V=\frac{4}{3} \pi r^3$

The radius is given by $r=\frac{d}{2}=\frac{42}{2}=21$

Volume of the sphere:

The volume of the sphere is given by

$V=\frac{4}{3} (3.14)(21)^3$

Simplifying, we get;

$V=\frac{4}{3}(3.14)(9261)$

Multiplying the terms, we have;

$V=\frac{116318.16}{3}$

Dividing, we get;

$V=38772.7$

Thus, the volume of the sphere is 38772.7 cubic cm.
