  1. 4cm

  2. 1cm

  3. 2cm

  4. 3cm

C Correct answer
Explanation

Curved surface area = 2 * pi * r * h = 88. Given h = 14, 2 * (22/7) * r * 14 = 88. This simplifies to 88 * r = 88, so r = 1 cm. Diameter = 2 * r = 2 cm.

AI explanation

Using the curved surface area formula for a cylinder, which is two times pi times radius times height, we substitute the given values to get 88 equals 2 times 22 over 7 times radius times 14. Simplifying this equation gives 88 equals 88 times radius, which means the radius is 1 cm. The diameter is twice the radius, so the diameter of the base is 2 cm.
