Multiple choice

A cylindrical water storage tank needs to be filled. The tank has a radius of 3.5 meters and a height of 10 meters. What is the maximum volume of water (in liters) that the tank can hold? (Use π=22/7 and assume 1 cubic meter = 1000 liters)

  1. 5,64,000

  2. 3,85,000

  3. 796,000

  4. 544,000

  5. 236,000

B Correct answer
Explanation

Volume = pi * r^2 * h = (22/7) * (3.5)^2 * 10 = (22/7) * 12.25 * 10 = 22 * 1.75 * 10 = 385 cubic meters. 385 * 1000 = 385,000 liters.

AI explanation

The volume of a cylinder is calculated as pi times the radius squared times the height. Substituting the given values gives (22 divided by 7) times 3.5 squared times 10, which simplifies to (22 divided by 7) times 12.25 times 10, equaling 385 cubic meters. Since 1 cubic meter equals 1000 liters, the maximum volume of water the tank can hold is 385 times 1000, which is 385000 liters.
