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.
Here π stands for the ratio of the
diameter of a circle to its circumference, and stands for the radius of the
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
Go through the following video, to
