9 cm 3 cm use 3.14 for the radius do not round
The volume of a cylinder is calculated using the formula V = πr^2h, where r is the radius and h is the height.
Given the radius r = 3 cm and height h = 9 cm, we can substitute these values into the formula:
V = π(3)^2(9)
V = π(9)(9)
V = π(81)
V = 81π
Therefore, the volume of the cylinder is 81π cubic centimeters.
