    1. Best Answer

      Curved surface area of cylinder 88 cm² and height h = 14 cm
      Let, the radius of base of cylinder = r cm
      Curved surface area of cylinder = 2πrh
      ⇒ 88 = 2 × 22/7 × r × 14 ⇒ 88 = 88r ⇒ r = 1 cm
      Hence, the diameter of base of cylinder = 2r = 2 × 1 = 2 cm.
