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?

Answer 1

\(V=\pi r^2 h\)
We need \(3V\).

Answer 2

V=πr2h
pi = 3.14 , r = 4 ft , h = 7 ft
Volume of cylinder is pi*r^2*h
V = 3.14*4^2*7 = 351.68 ft^3
For 3 cylinders, V = 3*351.68 =1055.04 ft^3

Answer 3

thanks!!!!!
