Question

Steve needs to find the circumference of a circle with a diameter of 12 inches. He uses a calculator to find the circumference. Which answer is

reasonable?
36.063912 in
40.963413 in
40.115921 in
37.699111 in

Answer 1

r = 12/2 = 6 π = 3.14

Circumference of a circle: C = 2πr



2*3.14*6
6.28*6 = 37.68 or 37.69

The last options seems reasonable

Hope that helps!
