Question

Find the area of a circle having a circumference of 12

Answer 1

The formula for the area of the circle --- A = pi x r^2
we dont have R but we do have a circumference so we can get r by using the formula --- C =2 x pi x r

12/2 x pi = r
r = 1.9

going back to the area formula --- A = pi x (1.9)^2 = 11.46

Answer 2

a=3.14r^2 so 3.14x 6 which is your radius to the power of 2 A=113.1
