The radius of the circle shown to the right is 3 inches. What is the area of this circle, in square inches?

(A) 3π (B)9π (C) 12π (D) 36π

The formula for the area of a circle is pi*r^2, where r is the radius of the circle. Since the radius is 3 inches, the area is pi*(3)^2 or 9*pi square inches.

Hope this helps!
