The volume of a sphere can be calculated as V= 4/3pir^3 where r is it’s radius. If the volume of a sphere is 87.1137 cubic feet, what is the radius? Round your answer to the nearest hundredth of a foot.
What is the radius and how do I find it

R=2.75

Step-by-step explanation: How to find the radius of a sphere?

This question seems very easy at first. You only have to find the center of the sphere and measure the distance to any point on its surface. However, how can you find this center in real, physical sphere, especially when it's closed? Let's look on a two of my suggestions:

Find the diameter. You can use two parallel planes and put the sphere between them. The distance between those plates equals the diameter of a sphere.

Find the volume. Prepare a graduated cylindrical container filled with water. Put a sphere into this cylinder, then bring out the sphere and measure the volume of displaced water
