The equation for the area of a circle is derived with integration.
Formula for Area of a Circle
By Steven Ellis
This video shows that pi is equal to the ratio of the area of a circle to the area of a square when the radius of the circle equals the length of the side of the square. This is a view of pi other than the ratio of the circumference to the diameter.
Area - Area Of A Circle

Circles: radius, diameter, circumference and Pi | Geometry | Khan Academy
By Khan Academy
The radius is the distance between the center and any point on the circumference of a circle. The diameter is always twice the radius. The circumference is the perimeter of the circle.
Area of inscribed equilateral triangle (some basic trig used) | Circles | Geometry | Khan Academy
By Khan Academy
This video will give you a good feel for what inscribed figures are like. It uses some trigonometry to figure out what the area of an equilateral triangle inscribed in a circle is, given the circle's radius. NOTE: We don't actually need trigonometry to solve this problem. Notice that we can view the equilateral triangle as six identical 30-60-90 triangles, the hypotenuses of which are radii of the circle, then use the 30-60-90 triangle side length ratios to figure out the rest of what we need to know to solve the problem.
