Circle a has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. the diameter of circle b is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points) part c: what observation can you make about the value of pi for circles a and b? (2 points)

A: I will be using the formula Circumference = 2πr to determine the circumference of both circles.

For circle A:  

Circumference = 2πr

25.12               = 2π*4

25.12/8            = 8π/8

3.14                 =  π

3.14                 =  3.14

For circle B:

Circumference = 2πr

9.42                = 2π*3/2

9.42/3             = 3π/3

3.14                 =  π

3.14                 =  3.14

B:  I will be using the formula Area = πr² to determine the area of both circles.

For circle A:  

Area         = πr²

50.24       = π*4²

50.24/16       = 16π/16

3.14                 =  π

3.14                 =  3.14

For circle B:

Area         = πr²

7.065       = π*3/2²

7.165/16       = 9/4π/9/4

3.14                 =  π

3.14                 =  3.14

it is x equals 3   plese mark me really need it
