Question

Right answer = brainliest! :>

The radius of a cylindrical construction pipe is 2.5 ft. If the pipe is 20 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.

Answer 1

Answer:

Answer: The volume of the pipe is 412 cubic 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 (Length in this case)

Replacing with the values given:

V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet  (rounded)

In conclusion, the volume of the pipe is 412 cubic feet

Feel free to ask for more if needed or if you did not understand something.

Answer 2

Answer:

V = 392.5 cubic feet

Step-by-step explanation:

$v=\pi r^{2} h=\pi (2.5)^{2} (20)=\pi (6.25)(20)=125\pi$

$\pi =3.14$

$v=392.5cu.ft$

Hope this helps
