Well, in math you solve the perimeter of circles and such, and learn understanding of them to help you with circles in real life.
There are different formulae for calculating the lengths of the sides or altitudes, medians, etc; the measure of angles, the perimeter and area. Furthermore, these depend on the information available.There are different formulae for calculating the lengths of the sides or altitudes, medians, etc; the measure of angles, the perimeter and area.

Area: 1/2πr2 Perimeter: 1/2πd+d
2(length + height)= perimeter
Square is a special case of a rectangle and the same formula may be used to find the perimeter
