A barn silo, excluding the top, is a circular cylinder. The silo is 8 m in diameter and the height is 28 m. Find the volume.
Use 3.14 for pie
The volume of a cylinder can be calculated using the formula:
Volume = π * r^2 * h
where π is the mathematical constant pi (approximately 3.14), r is the radius, and h is the height.
Given that the diameter of the silo is 8 m, we can find the radius by dividing the diameter by 2:
r = 8 m / 2 = 4 m
Substituting the values into the formula, we can calculate the volume:
Volume = 3.14 * (4 m)^2 * 28 m
= 3.14 * 16 m^2 * 28 m
= 3.14 * 448 m^3
= 1409.92 m^3
Therefore, the volume of the barn silo is approximately 1409.92 cubic meters.
