Solved Examples on Square Footage of Circle Calculator

1. Calculate the area of a circle with a radius of 3 meters.
The formula to find the area of a circle is:

Area = π × (radius) 2

Substituting the given radius:

Area = π × (3) 2

Area = π × 9

Area = 9πsquare meters

2. Find the area of a circle with a radius of 8 inches.
Using the same formula:

Area = π × (radius) 2

Substituting the given radius:

Area = π × (8) 2

Area = π × 64

Area = 64πsquare inches

3. Determine the area of a circle with a radius of 12 feet.
Again, using the same formula:

Area = π × (radius) 2

Substituting the given radius:

Area = π × (12)2

Area = π × 144

Area = 144π square feet
