Question

A storage drum has a diameter of 7 feet and a height of 4 feet 3 inches how many gallons of chemicals cleaner can this drum hold

Answer 1

The answer is "1223.42 gallons".

Explanation:

Given:

`Diameter\ (d)= 7\ feet\\\\r=(d)/(2)=(7)/(2)=3.5\ feet\\\\h= 4\ feet\ 3\ inches\ = 4.25 \ feet \\\\`

Using formula:

`Volume = \pi r^2h`

Put the value into the above formula:

`= \pi (3.5)^2 (4.25)\\\\= 3.14 *12.25* (4.25)\\\\= 3.14 * 52.0625 \\\\=163.47625\\\\= 163.56 \ feet^3\\\\= 163.56 \ feet^3`

`\therefore \\\\1 \ foot^3 = 7.48051945\ US\ gallons\\\\`

Final answer:

`\to (163.56)(7.48) = 1223.42\ gallons`
