I'm assuming the hole is circular (since you used the word diamter). If not, the answer below is not correct, and you will need to provide more information on the shape of the hole. The formula for the volume of a cylinder is V = lπr2, where l is the length of the cylinder (or, in this case, the depth, 9 feet); π is "pi", the ratio of a circle's circumference to its diameter, or about 3.1416; and r is the radius of the cylinder, or half its diameter, or 1.5 feet. Substituting for the terms yields: V = 9 x 3.1416 x (1.5)2 = 9 x 3.1416 x 2.25 = (app) 63.6 cubic feet.
There are 3,634 liters (960 gallons) of water in a pool that is four feet in diameter and 8 feet deep.
Diameter = 26 feet so Radius = 13 feet Then volume = π*r2*h where h = 4 inches = 1/3 feet So V = 176.98 cu feet (to 2 dp)
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
There is 98.17477042 cubic feet of dirt in a 5 foot deep hole that is 5 foot across.
The volume is 70.685 cubic feet.
volume of a clylinder= pi(r^2)h plug in values= pi(.5^2)(5) equals about 3.92 cubic feet
There are 3,634 liters (960 gallons) of water in a pool that is four feet in diameter and 8 feet deep.
There are 1.77 cubic feet of volume per foot of length at 1.5' in diameter.
The volume is 19.635 cubic feet.
Diameter = 26 feet so Radius = 13 feet Then volume = π*r2*h where h = 4 inches = 1/3 feet So V = 176.98 cu feet (to 2 dp)
Without depth, the circle is a flat figure without volume ... zero cubic units.
A 14-inch diameter by 20 foot long pipe has a volume of: 21.38 cubic feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
To calculate the volume of water in a pipe, first convert the diameter to feet (28 inches = 2.33 feet). Then use the formula for the volume of a cylinder (V = πr^2h) where r = radius (half the diameter) and h = height. For a 2.33-foot diameter pipe and 1 foot height, the volume is roughly 17.19 gallons of water per foot.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
