Chapter 12.4, Problem 15PPS

To determine

The volume of the sphere whose radius is $7.2km$

Answer to Problem 15PPS

The volume of the sphere is $1563.45k{m}^3$

Explanation of Solution

Given:

  $r=7.2km$

Concept Used:

The volume of the sphere is given by the following expression:

  $V=\frac{4}{3}\pi r^3$

Where,

Radius of sphere: $r$

Calculation:

The volume of the sphere is given by the following expression:

  $V=\frac{4}{3}\pi r^3$

Put the given data in eq.

  $\begin{array}{l}V=\frac{4}{3}\pi r^3\\ V=\frac{4}{3}\pi {\left(7.2\right)}^3\\ V=1563.45k{m}^3\end{array}$

Conclusion:

Hence, the volume of the sphere is $1563.45k{m}^3$
