Question

Find the circumference of both circles. Use 3.14 for pi

larger circle: about (BLANK) in.
smaller circle: about (BLANK) in.

Answer 1

1) C = 75.36 in.

2) C = 50.24 in.

Explanation:

Circumference of larger circle:

Radius = 12 in.

C = 2πr

C = 2(3.14)(12)

C = 75.36 in.

Circumference for smaller circle:

Radius = 12 - 4 = 8 in.

C = 2πr

C = 2(3.14)(8)

C = 50.24 in.
