Question

The diameter of a cylindrical construction pipe is 5 ft. If the pipe is 28 ft long, what is its volume?Use the value 3.14 for T, and round your answer to the nearest whole number.Be sure to include the correct unit in your answer.

Answer 1

Answer:

$V=550ft^3$

Explanation:

Here, we want to get the volume of the cylindrical construction pipe

Mathematically, we can calculate that by using the formula below:

$V\text{ = }\pi\times r^2\times h$

where r is the radius of the pipe (which is half the diameter 5 ft/2 = 2.5 ft)

h is the length of the pipe which is given as 28 ft

pi is given as 3.14

Substituting these values, we have it that:

$V\text{ = 3.14 }\times2.5^2\times28=549.5ft^3$

To the nearest whole number, we have this as:

$V=550ft^3$
