Multiple choice

If the volume and radius of the base of a cylinder are 1232 cm3 and 7 cm, respectively, its height is

  1. 10 cm

  2. 8 cm

  3. 18 cm

  4. 4 cm

B Correct answer
Explanation

Volume of cylinder = pi * r^2 * h. 1232 = (22/7) * 7^2 * h. 1232 = 22 * 7 * h. 1232 = 154 * h. h = 1232 / 154 = 8 cm.

AI explanation

The volume of a cylinder equals pi times the square of the base radius multiplied by the height. Substituting the given values gives 1232 equals pi times 49 times the height, which simplifies to 1232 equals 154 times the height. Solving for the height gives 8 cm.
