**Ms. Sue**, Saturday, May 5, 2012 at 6:55pmC = pi * d

37.68 = 3.14 * d

37.68 / 3.14 = d

12 = d

**Bosnian**, Saturday, May 5, 2012 at 7:09pmCircumference :

C = 2 r pi

C = 2 r pi Divide both sides by 2 pi

C / 2 pi = r

r = C / 2 pi

r = 37.68 / ( 2 * 3.14 =

r = 37.68 / 6.28

r = 6 cm

Area:

A = 4 r ^ 2 pi

A = 4 * 6 ^ 2 * pi

A = 4 * 36 * pi

A = 144 pi

A = 144 * 3.14

A = 452.16 cm ^ 2
