To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice. To find the radius when you are given the area of thequarter circle, multiply the given area by 4, then plug this number in for A into the formulaA = pi * r^2 and then solve for r.
