The diameter of a cylindrical construction pipe is 4. If the pipe is 22 ft long, what is its volume?
Use the value 3.14 for pi, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
To find the volume of a cylinder, you use the formula V = πr^2h, where r is the radius of the cylinder and h is the height (or length) of the cylinder.
First, since the diameter of the pipe is given as 4, the radius (r) would be half of the diameter, so r = 2 ft.
Next, we plug in the values into the formula:
V = 3.14 * (2)^2 * 22
V = 3.14 * 4 * 22
V = 3.14 * 88
V = 276.32
Rounding to the nearest whole number, the volume of the cylindrical construction pipe is 276 cubic feet.
