This construction video will provide brief information on the formula derivation toward circle area. To estimate the area of a circle, the formula A=(πR^2) is applied. You will gather knowledge on the origin of the formula and the importance of it.

In geometry, the area surrounded with a circle of radius r is πr2. Here, π symbolizes a constant, roughly equivalent to 3.14159, that is the same as the ratio of the circumference of any circle to its diameter

Go through the following video, to get the detailed process.
