    XY = (40/360)*(Circumference)

    Well, I see that the angle is 40 degrees. I'm trying to think what part of the entire circle that is. How many degrees are in the whole circle?

    I did: 360/40= 4 then I did: 2 x 3.14 x 9= 56.52 then I multiplied them both (4 x 56.52) and I got 508.98

    so XY = (40/360)*(Circumference) XY = (40/360)*(56.52) XY = ???
