The figure shows how to formula of the circumference of a circle may be used to drive the formula for the area of a circle based on the figure, which of the following represents the area of a circle a a equal pi R times are 2BA equal R times are CA equal two pi R times pi two equal two pi times are times are
The correct formula for the area of a circle based on the figure is:
A = πr^2
where:
A = area of the circle
r = radius of the circle
