Answer:

radius= 147.89

We just got done learning this in geometry and I was pretty good at it so it should be correct :)

Step-by-step explanation:

Here's the process I did to get it

C=2(3.14)r

94.20=2(3.14)r

(divide both sides by 2(3.14))

[tex]\frac{94.20}{2(3.14)} = \frac{2(3.14)r}{2(3.14)}[/tex]

                  ^

               this cancels out

r= [tex]\frac{94.20}{2(3.14)}[/tex]

(enter it into a calculator)

r= 147.89
