Web11 rowsfind out the area of a circle with a diameter of 3 inches using a simple calculator and the formula pi times the square of the radius.

Or, when you know the diameter:

A = π r2.

Thus, the square inches of the circle is π × (1. 181 in)² = 4. 3825 in², which is 4. 3825 square inches.

A = (π/4) × d2.
