We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.
We know that height of sphere is equal to its radius. This means that .
Using , we will get:
Upon comparing volume of sphere and volume of cylinder, we can see that volume of sphere is times volume of cylinder.
Therefore, the volume of the sphere would be 28 cubic meters.
