Multiple choice

How many liters of water are required to completely fill the cylindrical tank of inner radius 4 inch? (1) The curved surface area from the out side of the tank is 80 square inch. (2) The depth of the tank is 10 inch.

  1. Statement (1) ALONE is sufficient, but statement (2) ALONE is not sufficient.

  2. Statement (2) ALONE is sufficient, but statement (1) ALONE is not sufficient.

  3. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

  4. EACH statement ALONE is sufficient.

  5. Statements (1) and (2) TOGETHER are NOT sufficient.

AI explanation

To find the required volume in liters, we must calculate the volume of the cylinder using V = πr²h, which requires knowing both the inner radius and the depth. Statement 2 directly provides the depth as 10 inches, and when combined with the given inner radius of 4 inches, the volume can be found and converted to liters. Statement 1 only provides the outer curved surface area, which is insufficient without the outer radius or thickness. Statement 2 alone is sufficient, but statement 1 alone is not.
