OpenStudy (anonymous):

OpenStudy (anonymous):

@slynnec do you know i am bad at circles?

OpenStudy (anonymous):

I know what the circumference is, but I don't know what it is in terms of pi.

OpenStudy (anonymous):

3.14

OpenStudy (anonymous):

Right, but when you do the formula, which is C=2pi(r) you get 62.8 as the circumference. Oh, I just got it. The answer is B, because 20pi = 62.8.
