a cylindrical oil drum is 6 feet long and has a radius of 2.5 feet?
A-to the nearest cubic foot,what is the volume of this drum?
The formula to use is
V = pi r^2 L
Using pi = 3.14 will be accurate enough in this case.
L is the length and r is the radius..
Round off your calculated answer as they have requested.
118 cubic feet
To find the volume of a cylindrical oil drum, we can use the formula for the volume of a cylinder: V = πr^2h, where V is the volume, r is the radius, and h is the height.
In this case, the radius is given as 2.5 feet and the height is given as 6 feet.
First, let's calculate the volume:
V = π(2.5)^2(6)
V = π(6.25)(6)
V = 37.5π
To find the volume to the nearest cubic foot, we need to convert the volume from cubic feet to the nearest whole number. Since π is an irrational number, we'll round it to a reasonable approximation of 3.14.
V ≈ 37.5 × 3.14
V ≈ 117.75
Therefore, the volume of the cylindrical oil drum is approximately 118 cubic feet.
