Question

What's the volume of a pipe at a port that is 4 feet in diameter 24 ft long

A. 603.1872
B. 150.7968
C. 314.1632
D. 301.5936

Answer 1

answer: D

Step-by-step explanation:

volume is equal to length * surface area.

surface of a tube base is a circle, so it' surface are can be calculated as:

`\pi \: {r}^(2)`

where r is a radius

`r \: = (1)/(2) diameter`

so you calculate volume V as:

`v \: = \pi( {r}^(2) ) * length \: = \pi * (1)/(4) * {diameter}^(2) * length`

`v = 3.14 * (1)/(4) * 4 * 4 * 24 = 301.44`

so the answer is D
