Question

the radius of a cylindrical construction pipe is 2.5 ft. if the pipe is 21 ft long, what is its volume? use the value 3.14 for pi and round your anwser to the nearest whole number be sure to include the correct unit in your anwser

Answer 1

Explanation:

Pi x r^2 x h

Pi x 2^2 x 23

= 289 ft^3

Hope this helps :-)

Answer 2

Answer: The volume of the pipe is 412 cubic feet

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
