How many square inches are in a 12 inch diameter circle?
Area of circle: pi*6 squared = 36*pi square inches
How many cubic inches are in a cylinder that is 12 inches diameter by 36 inches tall?
Area of 12 inches diameter cylinder = pi.r2 = pi*62 = 36*pi square inches (r = radius = 6 inches). Volume = area * height = 36*pi*36 = 1296*pi = 4071.5 cubic inches (to nearest 1st decimal). (pi = 3.14159 to nearest 5th decimal).
How many inches are a diameter?
The inches in a diameter = 2 X inches in the radius. Or, inches in a diameter = inches in circumference / pi
