What is the area of a circle that is 120 ft in circumference?

Answer 1

Circumference of circle = 2 x pi x r where r is the radius. So we have here

120 = 2 x pi x r or

60 = pi x r or

60 = 3.1415 x r, Hence r = 60/3.1415 = 19.099

Area of circle is pi x r x r, here it is 3.1415 x 19.099 x 19.099 = 1145.93 square feet
