A circle has a radius of 43 meters. What is the area, in square meters, of the circle?

Question

Accepted Answer

Choice D is correct. The area, A , of a circle is given by the formula A = &#960; r 2 , where r is the radius of the circle. It&rsquo;s given that the circle has a radius of 43 meters. Substituting 43 for r in the formula A = &#960; r 2 yields A = &#960; 43 2 , or A = 1,849 &#960; . Therefore, the area, in square meters, of the circle is 1,849 &#960; . Choice A is incorrect. This is the area, in square meters, of a circle with a radius of 43 2 meters. Choice B is incorrect. This is the area, in square meters, of a circle with a radius of 43 meters. Choice C is incorrect. This is the circumference, in meters, of the circle.
