No that isn't the answer.. You have to plug in the information they have given you.
The r in this formula represents 12, the radius. While m represents the measure of the length they gave you, 10pi.

I'm sorry, I know how to do this, but I can't figure out the 10pi being the measure.. Usually its a degree..

A=(πr^2)/2πr*10π=5πr=5π*12=60π

does the / mean a fraction like (pi)(r)^2 over something else?
