The diameter and height of a right circular cylinder are equal to the diameter of a sphere. Find the ratio of volumes of cylinder and sphere.

Explanation

To find the ratio of the volumes of a right circular cylinder and a sphere, given that the diameter and height of the cylinder are equal to the diameter of the sphere, we can follow these steps:

### Step 1: Define the radius of the sphere
Let the radius of the sphere be \( r \). Therefore, the diameter of the sphere is:
\[ \text{Diameter of sphere} = 2r \]
