Multiple choice

The curved surface area and the base radius of a right circular cylinder are 4.4 cm2 and 0.7 cm, respectively. Find the height of the cylinder.

  1. 2 cm

  2. 10 cm

  3. 0.5 cm

  4. 1 cm

D Correct answer
Explanation

Curved surface area = 2*pi*r*h = 4.4. 2 * (22/7) * 0.7 * h = 4.4. 4.4 * h = 4.4. h = 1 cm.

AI explanation

The curved surface area of a cylinder equals 2 times pi times radius times height. Substituting the given values gives 4.4 equals 2 times 3.14 times 0.7 times the height. Simplifying the right side yields 4.4 equals 4.4 times the height. Solving this shows the height is 1 cm.
