volume of cylinder radius of 3 height of 9
use 3.14 for pie do not round
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 radius (r) is 3 and the height (h) is 9, we can plug these values into the formula:
V = 3.14 * 3^2 * 9
V = 3.14 * 9 * 9
V = 3.14 * 81
V = 254.34
Therefore, the volume of the cylinder is 254.34 cubic units.
