volume of the cylinder rounded to the nearest whole number? Use 3.14 for pi.

A.)452 ft3
B.) 1,809 ft3
C.)151 ft3
D.)603 ft3

Answer 1

Given:

A cylinder has a circular base with a diameter of 12 ft.

The height of the cylinder is 4 ft.

To find:

The volume of the cylinder.

Solution:

We have,

Height = 4 ft.

Diameter = 12 ft.

Radius =
`(12)/(2)` ft

=
`6` ft

Volume of a cylinder is

`V=\pi r^2h`

Where, r is the base radius and h is the height of the cylinder.

Putting
`\pi=3.14` r=6 and h=4, we get

`V=(3.14) (6)^2(4)`

`V=(3.14)(36)(4)`

`V=452.16`

`V\approx 452`

So, the volume of the cylinder is 452 cubic ft.

Therefore, the correct option is A.
