1. If the area of a sector of a circe is = 18(pi) cm sqaured and the radius is 6 cm, what is the measure of the central angle in degrees? FIrst off, lets look at what we have. We have:
Next, we are going to see what the area of a sector is equal to: Asector = (degrees)/360 * area of circle Now, substitute: 18(pi) = x/360 * 36(pi) 1/2 = x/360 x = 180 Good luck!!
