Question

The volume of a sphere is 29307 cubic centimeters. What is the radius of the sphere?

Round to the nearest whole number.

Answer 1

19 cubic centimeters

Explanation:

The equation for the volume of a sphere is
`(4/3)\pi r^3`.

We can setup the equation as
`29307 = (4)/(3)\pi r^3`.

Now we need to isolate the r^3. Divide both sides by 4/3 and pi, which leaves
`(29307)/((4/3) \pi ) =r^3`

Now we take the cube root of both sides to have a single r on the right side. This comes out to equal 19 cm^3
