Given:

Radius = 7r in

Let's find the volume of the sphere.

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

[tex]V=\frac{4}{3}\pi r^3[/tex]

Where:

r is the radius = 7 in

Thus, we have:

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

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

ANSWER:

1437 in³
