...radius, which is all you need to find the area of the circle. You square the radius... the whole circle, and the area of the sector . You also know that the angle of a full circle is 360 degrees...

Use these steps: 1) Find the area of circle. = π r² 2) Divide that by 2, to get the area of semicircle 3) divide that by 3, to get the area of each segment = π r²/6 =π 8*8/6 =10.6 π =33.52 square units/
