To find the volume of a cylinder, you can use the formula V = πr^2h, where V is the volume, π is approximately 3.14159, r is the radius of the base, and h is the height.
The given diameter is 8 inches, so the radius would be half of that, which is 4 inches.
Using the values, we can calculate the volume V = 3.14159 * 4^2 * 12 = 3.14159 * 16 * 12 = 602.88 cubic inches.
Therefore, the correct answer is 602.88 cubic inches. Answer choice: • 602.88 cubic inches.
