Tamara needs to buy motor oil to fill 3 empty cylindrical barrels at her oil service center. Each barrel is 7ft deep and has a radius of 4ft. What is the volume of oil needed? Use 3.14
AAAaannndd the bot gets it wrong yet again!
3 * π * 4^2 * 7 = 1055
To find the volume of oil needed, we can use the formula for the volume of a cylinder:
Volume = π * r^2 * h
Given:
Radius of each barrel (r) = 4 ft
Depth of each barrel (h) = 7 ft
Plugging in these values into the formula, we get:
Volume = 3.14 * 4^2 * 7
= 3.14 * 16 * 7
= 3.14 * 112
= 351.68 cubic feet
Therefore, the volume of oil needed to fill the 3 empty cylindrical barrels is 351.68 cubic feet.
To find the volume of oil needed to fill the cylindrical barrels, we need to use the formula for the volume of a cylinder, which is given by V = πr^2h, where V is the volume, r is the radius, and h is the height (or depth) of the cylinder.
In this case, the radius is 4ft, and the height (or depth) of the cylindrical barrels is 7ft. The value of π that we are given to use is 3.14.
To find the volume of one barrel, we can substitute the given values into the formula:
V = 3.14 * (4ft)^2 * 7ft
Simplifying this expression, we have:
V = 3.14 * 16ft^2 * 7ft
V = 3.14 * 112ft^3
V = 352.48ft^3
Since we need to fill three barrels, we can multiply the volume of one barrel by 3:
Total volume = 352.48ft^3 * 3
Total volume = 1057.44ft^3
Therefore, Tamara needs approximately 1057.44 cubic feet of motor oil to fill all three empty cylindrical barrels at her oil service center.
