3.14 * ((5.2 / 2)^2) = 21.2264
for pi = 3.14159265
pi * ((5.2 / 2)^2) = 21.2371663
Note: the unit of the diameter is not specified so the unit^2 of area is unknown.
Area = pi*52 square yards
Area of the circle = pi*radius2 = pi*52
2123.7165 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 = pi*262 = 676*pi square mm
Area = pi*52 = 78.539 square cm to 3 dp
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
The circumference of a circle if the diameter is 52 is 163.4 units.
Area = 1/4*Pi*d2 = 0.25*3.14*52(25) = about 19.63ft2
Area = Pi(d/2)2 = Pi*52 = approximately 78.54 inches2
From Wolfram Alpha: radius | 26/pi inches8.276 inches diameter | 52/pi inches16.55 inches area | 676/pi in^2 (square inches)215.2 in^2 (square inches)
Area = pi*52 = 78.53981634 or rounded to 2 decimal places as 78.54 square cm
The circumference of a circle, C, is pi*diameter. If 52 is the diameter, then the equation becomes: C = 3.14159 * 52 or C = 163.36 inches.
