what is area of circle?

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle. The unit of area is the square unit, for example, m², cm², in², etc. Area of Circle = πr² or πd²/4 in square units, where (Pi) π = 22/7 or 3.14. Pi (π) is the ratio of circumference to diameter of any circle. It is a special mathematical constant.

Given:

radius= 25 ft

Area of circle= πr²

                      =3.14 * 25 * 25

                      = 1962.5 ft²

Hence, the area covered is 1962.5 ft².
