A Correct answer
Explanation

The volume of a cylinder is calculated using the formula V = pi * r^2 * h. Substituting the given values: V = 3.14 * 4^2 * 8 = 3.14 * 16 * 8 = 401.92 cm^3.

AI explanation

To find the volume of the cylinder, we apply the formula V = pi * r^2 * h using the provided pi value of 3.14. Plugging in the radius of 4 cm and height of 8 cm gives V = 3.14 * 4^2 * 8. This calculates to 3.14 * 16 * 8 = 3.14 * 128 = 401.92 cubic cm. The volume of the cylinder is 401.92 cubic cm.
