    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.

    So:\[144 \left( 10\pi \right) \over 360\]

    A=pi r^2/2 pi r*10 pi=5 pi r=5 pi 12=60 pi

    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?
