The radius is squared and timed by pi (3.14) 28cm x 28cm x 3.14 = 2461.76cm2
The circumference of a circle with radius measuring 28cm is about 175.9cm (C = r x 2 x Pi).
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
The area of a circle with a radius of 14.4 is 651.4
Area of a circle = pi*radius squared
