Question

The radius of circle A is 6 ft . The radius of circle b is 5 ft 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 1 ft 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 c​?

Answer 1

Part 1

Circle A: 6

Circle B: 5

Circle C: 3+ CB

Circle D: 1-R of CC

Circle C:

5+3=8

Radius: 8

Circle D

8-1=7

Radius: 7

Circle C:8

Circle D:7

Part 2

Formula: PiR^2

Circle A:

6*6=36

36*3.14=113.04

Circle C:

8*8=64

64*3.14=200.96

200.96-113.05=87.91

87.91
