Question

A cylindrical diesel fuel holding tank has a radius of 6 feet and a length of 12 feet. What is the maximum volume of fuel the tank can hold? (to nearest whole number) A) 339 ft3 B) 679 ft3 C) 1,357 ft3 D) 2,714 ft3

Answer 1

Answer:
`1357\ ft^3`

Explanation:

The volume of a cylinder is given by :_

`\text{Volume}=\pi r^2 h`, where r is radius and h is height of the cylinder.

Given: Radius of cylindrical diesel fuel holding tank = 6 feet

Height of cylindrical diesel fuel holding tank =12 feet

Now, the volume of cylindrical diesel fuel holding tank is given by :-

`\text{Volume}=\pi(6)^2(12)\\\\\Rightarrow\text{Volume}=(3.14)(36)(12)\\\\\Rightarrow\text{Volume}=1357.16802635\approx1357\ ft^3`

Hence, the the maximum volume of fuel the tank can hold is 1357 cubic ft (to nearest whole number) .

Answer 2

volume of a cylinder is calculated as pi x radius x radius x height

pi is 3.14

so volume = 3.14 x 6 feet x 6 feet x 12 feet = 1356.48 ft3

so the correct answer is C)1,357 ft3
