Given – the diameter of the circle is 32 cm. You need to find 7/8 of the area of the circle. Decision. The area of a circle is pi (the radius of the circle) squared. Knowing that the diameter of the circle is 2 radii. The area of a circle is pi * diameter squared / 4 = 256pi cm squared. 7/8 of the area of a circle = 7 * 256pi / 8 = 224pi cm squared (knowing pi = 3.14). 7/8 of the area of the circle = 703.36 cm squared.
