The two outside edges are equal to the radius of the circle and the curved bit is a quarter of the circles circumference. So use the formula for circumference and divide by four to get the curved bit and add double the radius

Find the circumference of the circle and divide by 4 to get the curved edge of the shaded area. Then the other two lengths are just the radius of the circle i believe.
