The formula to find the area of a circle is A = πr2, where A is area, π is pi (3.14159), and r is the radius. The radius is half the diameter, 1/2d or d/2.
r = d/2 = 450mm/2 = 225mm
A = πr2 = 3.14159 x (225mm)2 = 15904mm2

The diameter of a circle with an area of 37.68 is 6.92
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.
The area of circle that has diameter of 14 centimeters is: 153.9 cm2
70685.8mm2 (rounded to the nearest tenth) The area of a circle can be found by the formula: A = pi * radius2, or A = pi * (diameter/2)2 Thus, A = pi * (300mm/2)2 = (22500*pi) mm2, or approximately 70685.8mm2
