Question

confused

Answer 1

\[r= \frac{C }{2\pi }\]

Answer 2

Well, that's the formula to get the radius. :)

Answer 3

\[\large Circumference~=~2\pi r\] To solve for r, get r alone. \[\large \frac{Circumference}{2\pi}~=~\frac{2\pi r}{2\pi}\]\[\large \frac{Circumference}{2\pi}~=~r\]

Answer 4

so D is right /... what do u 2 think

Answer 5

Yes, it would be D

Answer 6
