A Correct answer
Explanation

The volume of a cylinder is given by V = pi * r^2 * h. Substituting r = 3 and h = 6 gives V = pi * (3^2) * 6 = pi * 9 * 6 = 54pi.

AI explanation

Using the volume of a cylinder formula, V = πr^2h, we substitute the radius of 3 inches and the height of 6 inches. This results in the calculation π * 3^2 * 6, which simplifies to π * 9 * 6. Multiplying 9 by 6 yields a total volume of 54π cubic inches.
