16ft = 2πr π = 3.142 (a constant) -------- r is the radius 16/2π = r r = 16/6.284 r= 2.54 feet
The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.

The formula for the volume of a cylinder is V = πr2h, where π is pi (3.14159), r is radius, and h is height. To get the radius, you divide the diameter by 2. So the radius is 16ft/2 = 8ft. Now you can plug your known values into the formula: V = πr2h = (3.14159)(8ft)2(10ft) = 2010.6ft3
