The diameter of circle A is 8 inches. the diameter of circle B is 4 inches greater then the diameter of circle A. The diameter of circle C is 4 inches greater then the diameter of circle B the area of circle A is the area of circle B is the area of circle C

Step-by-step explanation:

radius of A = 4 in

area of A = 16π in²

radius of B = 6 in

area of B = 36π in²

radius of C = 8 in

area of C = 64π in²

Area of A is 16π/(36π) the area of B = 4/9 the area of B

Area of B is 36π/(64π) the area of C = 9/16 the area of B

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
