Volume = Cross-sectional area X Length. So Area of a circle = PI times radius². Approximate PI with 3.14, then radius = diameter / 2 = 3 inches. (pipe normally is specified in inside diameter).
So Area = (3 in)² x 3.14 = 28.26 in². Now multiply that by length of pipe (in inches) to find volume capacity (in cubic inches) of that section of pipe.
201 cubic inches
201.1 cubic inches for every inch long the piece of pipe is.
9,651 cubic inches for a 32-inch diameter x 12-inch long cylinder.
Volume = pi*2.752*6 = 142.5497667 cubic inches
0.135 cubic feet
Volume = pi*r2*h = pi*82*1= 201 cubic inches, approx.
18 x 3.14 = 56.52 56.52 x 2 = 113.04 The answer is 113.04 cubic inches.
A cylinder that has an 18-inch diameter and is 36 inches long has a volume of: 5.3 cubic feet.
V = pi*r2*h = pi*32*18 = 508.9 cubic inches
The volume is approximately 0.3315 cubic feet.
You can use the formula for the volume of a cylinder to calculate that.
volume=pir2h=3.1416x92x18=4580 cubic inches 4580x0.0173 quarts/cubic inch=79 quarts
