The stadium calculate to find the radius, side length, area, and perimeter of a stadium.

r = radius
a = length of side a
A = area
P = perimeter

For example, to a stadium, radius = 2, length of side a = 3:

To calculate A, use the following formula: πr² + 2*r*a. When you substitute r and a for their values, you get π(2² + 2*2*3, which equals 24.56637².
To calculate P, use the following formula: 2 * (πr + a). When you substitute r and a for their values, you get 2 * (π(2) + 3), which equals 18.56637.
