If the area of a circle is 58 square feet, find the circumference. a. 26.99 ft. b. 22.35 ft. c. 42.5 ft. d. 4.25 ft.

It's answer is option A. As the area of circle is given which is 58 square feet, we are to find circumference of the circle. We know that area = π r^2 Where π = 3.14 and r is radius of the circle So it will become 3.14 x r^2 = 58 r^2 = 58/3.14 r^2 = 18.4713375796 If we take square root of both sides, we get r = 4.297829403268585 feet By using this value of r we can find circumference of the circle, As, Circumference = 2 π r It will become 2 x 3.14 x 4.297829403268585 26.99036 Which is very close to the option A.
