Height of cylinder, h = 14cm
Let the diameter of the cylinder be d
Curved surface area of cylinder = 88 cm2
We know that, formula to find Curved surface area of cylinder is 2πrh.
So 2πrh =88 cm2 (r is the radius of the base of the cylinder)
2×(22/7)×r×14 = 88 cm2
2r = 2 cm
d =2 cm
Therefore, the diameter of the base of the cylinder is 2 cm.
The curved surface area of a right circular cylinder of height 14 cm is 88cm^2 . Find diameter of the cylinder.(π=22/7).
