B Correct answer
Explanation

Volume of a cylinder = pi * r^2 * h. Using pi = 22/7, Volume = (22/7) * 3^2 * 21 = 22 * 9 * 3 = 594.

AI explanation

Using the formula for the volume of a cylinder, the volume equals pi times the radius squared times the height. Substituting the given values, we calculate 22/7 times 9 times 21. The result is 594 cubic units.
