Question

An construction company poured a cylindrical shaped concrete column 15 feet long with a radius of 3 feet. How much concrete did it take to make the column, in terms of π?

Answer 1

`135\pi\ ft^3`

Explanation:

we know that

The volume of a cylinder (concrete column) is equal to

`V=\pi r^(2)h`

we have

`r=3\ ft\\h=15\ ft`

substitute

`V=\pi (3)^(2)(15)`

`V=135\pi\ ft^3`
