Question

The radius of Circle A is 3 in. The radius of Circle B is 3 in. greater than the radius of

Circle A. The radius of Circle C is 3 in. greater than the radius of Circle B. The radius of Circle D is
2 in. 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?

The area of Circle A is __in. 2

Answer 1

Area of A: 9pi

5.4 Times greater

Explanation:

Circle A Radius: 3

B Radius: 3+A (6 total)

C Radius: 3+B (9 total)

D Radius: C-2 (7 total)

Area of each Circle using formul pi*radius²

A: 9pi

B: 36pi
C: 81pi

D: 49pi

49/9 = 5.4 Circle D is 5.4 times greater then A
