The diameter of the base of a right circular cylinder is 42cm and its height is 10cm. Find the volume of the cylinder.

Explanation

To find the volume of a right circular cylinder, we can follow these steps:

### Step 1: Identify the diameter and calculate the radius
The diameter of the base of the cylinder is given as 42 cm. To find the radius, we use the formula:
\[ \text{Radius} (r) = \frac{\text{Diameter}}{2} \]
Substituting the given diameter:
