Question

The radius of circle A is 7ft . The radius of circle B is 3ft greater than the radius of circle A. The radius of circle C is 3ft greater than the radius of circle B . The radius of circle D is 1ft less than the radius of circle C. What is the area of each​ circle? How many times greater than the area of circle A is the area of ​circle D?

Answer 1

Area of A = 49pi ft^2 = about 157.079 square feet

Area of B =100pi ft^2 = about 314.159 square feet

Area of C = 169pi ft^2 = 169(3.14159) = 530.93 square feet

Area of D = 144pi ft^2 = 452.39 square feet

Area of D is about 3 times Area of A

Area of D = 144/49 times the Area of A = about 2.939 times greater
