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

the formula is pi times r squared pi = 3.14 r = 3 3 squared = 9 so its 3.14 times 9
Entire surface area of a cylinder = (2*pi*radius2)+(pi*diameter*height)
648pi. (pi = 3.14159...)Area of a circle = (pi) x (radius squared)= (pi)(9 squared) = (pi)81.Area of a cylinder = area of circle x height.= (pi)81 x 8= 648(pi)
circumference = 2*pi*9
