Question from mae, a student:

what are the formulas on getting the area of the square outside an inscribed circular region?

Hi Mae,

The area of a rectangle is the length times the width. In a square the length and width are equal so the area of a square is the length times itself.

Suppose the radius of the circle is r.

circle and square

What is the length of a side of the square?
