pi x r x r x length. 3/2 is 1.5 = radius. So all figures pluged in is 42.41 in3
1.963 cubic feet
13.1 cubic yards, approx.
volume=pir2h=3.1416x92x18=4580 cubic inches 4580x0.0173 quarts/cubic inch=79 quarts
29.45 cubic feet or 183.45 US gallons.
489.76 gallons of water.
Assuming it is 9 INCHES deep, Vol = pi*r2*h = pi*(d2/4)*h = 19113 cubic inches (approx).
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
Depends on the depth. If it is 4 feet deep and it is cicular with a diameter of 24 feet then you have approx. 13,553 gallons of water. If it is 3 feet deep then you have approx. 10,152 gallons of water.
In cubic inches it is: pi*4.5*4.5*24 = 486*pi or about 1527 rounded
Without depth, the circle is a flat figure without volume ... zero cubic units.
Three acres three inches deep is 403.33 cubic yards.
A Cubic Foot Is 12 Inches Wide X 12 Inches High X 12 Inches Deep. 12 X 12 X 12.
