Sandra has a mailing cylinder for poster that measures 24in long and 4in in diameter. What is the volume of the tube?

1 answer

The formula to calculate the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.

Given that the diameter of the cylinder is 4 inches, the radius is half of that:
r = 4/2 = 2 inches

The height of the cylinder is 24 inches.

Now we can plug in these values into the formula:

V = π(2)^2 * 24
V = π(4) * 24
V = 4π * 24
V = 96π

Using an approximate value for π of 3.14, we can calculate the volume:

V ≈ 96 * 3.14
V ≈ 301.44 cubic inches

Therefore, the volume of the mailing cylinder is approximately 301.44 cubic inches.
