area of a circle = pi r squared = pi x (9 squared) = 254.47 to 2 decimal places

Area of circle = pi * radius squared A = pi(4.4 cm)^2 = 60.8 centimeters squared ( call it 61 cm^2 )

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 formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)

Using 3.14 as Pi the area of circle is: 2461.76
