the formula for circumference is \[C = 2\pi r\]
does that help?

Answer 3

and radius =r.

Answer 4

the ratio of a circle's circumfrence to it's diameter is pi and radius is (1/2) diamter. hope that helps

Answer 5

notice if we have a/b and want (1/2)b then we have a/((1/2)b) = (a/(b/2)) = 2(a/b)

Answer 6

thank u
