The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
It is 18 centimeters because your radius is exactly half of the diameter in any circle
circumference=pi*diameter so diameter=circumference/pi 36/pi=11.4591559
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
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
area of circle is πr² (3.14)(6)² 3.14 * 36 = 113.45 cm² ■
Area of the circle: pi*6 squared = 36*pi square inches
