1.  Area of a square = Side × Side = S2

2.  The area A of a triangle is given by the formula A=(1/2)*b*h where b is the base and h is the height of the triangle.

3.  The area of a circle is pi times the radius squared (A = π r²)

4.  Since the diameter is twice the radius, the circumference of a circle is a product of pi and 2r, i.e. 2(pi)*r.
