The correct formula for finding the area of a circle is A=πr2, which means the area is equal to pi times the radius squared. This formula is derived from the formula for the area of a circle, which is π times the diameter squared divided by 4 (A=πd2/4). Therefore, the correct formula is A=πr2, where r is the radius of the circle.
choose one of the four i listed
A=πr2
