Answer:

the diameter of the cylinder is 2cm.

Step-by-step explanation:

Given , The height of cylinder =14cm

and , the curved surface area of cylinder =88cm²

we know that , the curved surface area of cylinder =2πrh

and 2r=d

here , r=radius of cylinder , d=diameter of cylinder and h=height of cylinder

so , the curved surface area of cylinder = πdh = 88cm ²

π × d × 14 =88

22/7 × d × 14 =88

d=2cm
