Best ResponseYou've already chosen the best response.2I did that incorrectly. I realized what I did @RicardoDelfin So, @joannacaro123 the other equation is \[C=(\pi)2r\]

Best ResponseYou've already chosen the best response.2You could put back 36 in for C. From there you would divide and get what r is equal to.
