Question

The radius of the cylindrical construction pipe is 2.5ft, if the pipe is 25ft long, what is the 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

Explanation:

r = 2.5 ft

h = 25 ft

Volume of cylindrical pipe = πr²h

= 3.14 * 2.5* 2.5 * 25

= 490.625 {as tenth place value is ≥ 5, add 1 to the whole number}

= 491 cubic feet
