find the volume of a cylinder with a height of 12 inches and a diameter of 9 inches use 3.14 for pi
To find the volume of a cylinder, you can use the formula V = πr^2h, where r is the radius of the cylinder and h is the height.
Given that the diameter of the cylinder is 9 inches, the radius (r) is half of the diameter, so r = 9/2 = 4.5 inches.
Now, substitute r = 4.5 inches and h = 12 inches into the formula:
V = 3.14 * (4.5)^2 * 12
V = 3.14 * 20.25 * 12
V = 3.14 * 243
V = 762.42 cubic inches
Therefore, the volume of the cylinder is 762.42 cubic inches.
