The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
The answer is 1017.87601976.
Area of a Circle = (pi)(r^2) Diameter = 2r If the diameter of the circle is 12, then the radius has to be 6. If the area of a circle is pi times the square of the radius, and the square of 6 is 36 (6x6), then the area of the circle is 36pi.
36 pi squinches
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Area of the circle: pi*6 squared = 36*pi square inches
Area of circle: 36*pi = 113.097 square cm to 3 decimal places
Divide the circumference of a circle by pi to obtain the diameter. Diameter of a 36 inch diameter circle is 36/3.1416 inches , or 11.459 inches.
