First find the area of the whole circle then divide by 2. If the whole circle is not provided, multiply 2 and pi (3.14). Then multiply the product by the diameter to get the whole area. (If only the radius is given, multiply it by two and multilply that product to 3.14 x 2.) Then divide the area by 2.
