The circle and rectangle, with radius and side lengths shown, have the same area. knowing this, which is a possible way to find the area of a circle? a. multiply the circumference by the diameter. b. multiply the circumference by half the radius. c. multiply twice the circumference by the diameter. d. multiply twice the circumference by half the radius.

B

Step-by-step explanation:

The point to this question is that the rectangle and the circle have the same area.

The circumference of a circle is 2*pi*r. You want to wind up with pi r^2

Area = (2 *  pi * r)  * (r/2) is what the rectangle tells you to do.

Area = Circumference * r/2 which is B. No other answer will give you this result.

Answer

the answer is d
