It's simply because the area of a circle is defined as pi * r * r.
Area of a circle is defined by the equation: A = pi * r2. pi = 3.14159 & r = 28. Substitute into the equation: A = 3.14159 * 282. Area = 2463 cm2.
In math the area of a circle is defined as pi*r^2 which is pi*32^2 or 1024*pi. This is approxometly 3216.99088. Hope that helped :)
