  2. 1.0 cm

  3. 1.5 cm

  4. 2.0 cm

D Correct answer
Explanation

Curved surface area = 2 * pi * r * h = 88. Given h = 14, 2 * (22/7) * r * 14 = 88. 44 * 2 * r = 88, so 88 * r = 88, r = 1. Diameter = 2 * r = 2 cm.

AI explanation

Applying the curved surface area formula for a cylinder, 88 equals 2*pi*r*14. Solving for the radius gives r equals 88 divided by 88, which is 1 cm. The diameter is twice the radius, so it is 2.0 cm.
