what's the volume of a cylinder with a height of 4ft and a length of 5ft
The volume of a cylinder can be calculated using the formula V = πr^2h, where r is the radius of the cylinder and h is the height.
In this case, since the length is given instead of the radius, we need to calculate the radius first. The radius of a cylinder is half of the length, so the radius of this cylinder would be 5ft / 2 = 2.5ft.
Now we can plug the values into the formula:
V = π(2.5)^2(4)
V = π(6.25)(4)
V = 25π ft^3
Therefore, the volume of the cylinder is 25π cubic feet.
