Question

What is the volume of a sphere with a radius of 9.1 ft, rounded to the nearest tenth of a cubic foot?

Answer 1

The volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.

We have given that, the radius of the sphere is 9.1ft.

We have to determine the volume of the sphere

What is the formula for the volume of the sphere?

The volume of the sphere  is given by

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

r is the radius of the sphere

V- is the volume of the sphere

So use the given value in the formula so that,

$V=\frac{4}{3}\pi (9.1)^3$

$V=3156.55082 ft^3$

Therefore the volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.
