Question

Find the volume of each sphere. Round to the nearest tenth, if necessary. Do not include units (i.e. ft, in, cm, etc.) (FR)

Answer 1

Explanation

The radius of a sphere is the distance from its center to its surface. Assuming a sphere with a radius r its volume is given by the following formula:

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

In this case the radius of the sphere is of 4.7 miles. Then we take r=4.7 and we find its volume:

$V=\frac{4}{3}\pi\cdot4.7^3=434.9$Answer

Then the answer is 434.9.
