The area of a full circle is pi x R squared where R = RADIUS The area of a semi circle is half of that, or pi x R squared/2

The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.

SA = 3,217 cm2

The diameter is twice the radius and so 2 times 16 = 32cm
