How do I find the radius if the circle is 6inches how do I solve

Answer 1

I do not know what you mean by "the circle is 6 inches"

Answer 2

I can only assume you mean that the circumference C=6 inches.

So, since C=2πr,
6=2πr
r = 3/π

Or, maybe you mean that the diameter is 6 inches. In that case, r=6/2 = 3 inches
