Let A be Area,D the Diameter, and #(pie) be 22/7
Therefore, Area(A) =# X D i.e (#multiply by D)
A=22/7 X 52
A=163.43 sq unit

Area of the circle = pi*radius2 = pi*52
Area = pi*52 = 78.53981634 or rounded to 2 decimal places as 78.54 square cm
Its area is: pi*52 = 25*pi or 78.539 cm to three decimal places
The formula for the area of a circle is A = pi x r2 where r is the radius. If the diameter of the circle is 10 meters, then the radius is half that amount or 5 meters. Plug that value into the formula for r, using 3.14 as an approximation for pi. The area is 3.14 x 52 or about 78.5.
Square footage is called "area". To find the area of a circle: A = pi x r2 So for a circle with a 10-inch diameter (which means a 5-inch radius): A = 3.141593 x (52) So the area = 78.54 inches
