Tamara needs to buy motor oil to fill the 3 empty cylindrical barrels at her oil service center. Each barrel is 7 feet deep and has a radius of 4 feet. What is the volume of oil needed? Use 3.14 for pi.

Respuesta :

Tamara needs to buy 1055.04 volume of oil to fill up 3 cylindrical barrels

Answer:

1055.04 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²h

Using 3.14 for π, 4 for r and 7 for h,

V = 3.14(4²)(7) = 351.68

There are 3 barrels; this gives us

351.68(3) = 1055.04 ft³
