what is the volume in cubic units of a cylinder with a radius of 9 units and a height of 4 units? assume that pi = 3.14

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

Given:
Radius = 9 units
Height = 4 units
π = 3.14

V = 3.14 * 9^2 * 4
V = 3.14 * 81 * 4
V = 3.14 * 324
V = 1016.56 cubic units

Therefore, the volume of the cylinder is 1016.56 cubic units.
