Question

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

Answer 1

The total volume of the three cylinders is given by:
V = (3) * (pi) * (r ^ 2) * (d)
Where,
r: cylinder radius
d: cylinder depth
Substituting values we have:
V = (3) * (3.14) * (4 ^ 2) * (7)
V = 1055.04 feet ^ 3
Answer:
the volume of oil needed is:
V = 1055.04 feet ^ 3
