The diameter of a cylindrical construction pipe is 4 ft. If the pipe is 16 ft long, what is its volume?

Use the value 3.14 for, and round your answer to the nearest whole number.

Be sure to include the correct unit in your answer.

Answer: 201 square feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder: π x radius² x height (in our case the length of the pipe)

Since:

Diameter = radius x 2

In our case D = 4

4 = 2radius

Radius = 4/2 = 2 ft

Now that we have the radius, we can use the volume formula replacing with the values given:

V = 3.14x 2² x 16 = 3.14 x 4 x16 = 200.96 = 201 square feet

201 ft³ (201 cubic feet)

Step-by-step explanation:

The volume of a cylinder is given as:

V = pi * r² * h

Where r = radius of the cylinder

h = length of the cylinder.

The diameter of the cylindrical pipe, d = 4 ft

The radius of the cylindrical pipe, r = d/2 = 4 / 2 = 2 ft

The length of the cylindrical pipe, h = 16 ft

The volume of the cylindrical pipe is:

V = 3.14 * 2² * 16

V = 200.96 ft³ = 201 ft³ (to the nearest whole number)

The volume of the cylindrical pipe is 201 ft³ (201 cubic feet)
