Tamara needs to buy motor oil to fill the three 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 3.14 for n
The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height (or depth, in this case) of the cylinder.
In this case, each barrel has a height of 7 ft and a radius of 4 ft. So, the volume of one barrel is:
V = π(4^2)(7)
V = 439.82 cubic feet (rounded to two decimal places)
To find the volume of all three barrels, we can multiply this by 3:
V = 3(439.82)
V = 1319.46 cubic feet
Therefore, Tamara needs 1319.46 cubic feet of motor oil to fill all three barrels.
