Question

What is the volume of the sphere below? Round to the nearest whole number.

Answer 1

Given:

Radius = 7r in

Let's find the volume of the sphere.

To find the volume of the sphere, apply the formula:

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

Where:

r is the radius = 7 in

Thus, we have:

$\begin{gathered} V=\frac{4}{3}*\pi *7^3 \\ \\ V=\frac{4}{3}*\pi *343 \\ \\ V=1436.7\approx1437\text{ in}^3 \end{gathered}$

Therefore, the volume of the given sphere rounded to the nearest whole number is 1437 cubic inches.

ANSWER:

1437 in³
