**Knights**, Thursday, April 4, 2013 at 9:24pmOh, if you meant c is circumference, then good. Basically, 2 pi r = circumeference

so, 2 pi r = 44

so, pi r = 22

so r = 22/pi

that is your answer, roughly 7.

(that is because pi is roughly 22/7, so 22/(22/7) = 7/22 * 22 = 7. But since pi is not exactly 7, it is a bit off, by about 3 thousandths to be exact)

**Ms. Sue**, Thursday, April 4, 2013 at 9:25pmC = circumference

C = pi * d

44 = 3.14 * d

44/3.14 = d

14.013 = d
