  1. Volume of the cylinder will be doubled.

  2. Volume of the cylinder will remain unchanged.

  3. Volume of cylinder will be halved

  4. Volume of the cylinder will be 1/4

B Correct answer
Explanation

Volume of a cylinder is V = pi * r^2 * h. New volume V' = pi * (2r)^2 * (h/4) = pi * 4r^2 * h/4 = pi * r^2 * h. The volume remains unchanged.

AI explanation

The original volume of the cylinder is πr2h. The new volume is π(2r)2(h/4), which simplifies to π(4r2)(h/4) or πr2h. Since the new volume equals the original volume, the volume remains unchanged.
