Answer:
12 cm.
Step-by-step explanation: Steps under the solution ,
Given :- Curved surface area of cylinder = 3168 cm^2
Height = 42 cm
We know that ,
2pirh = curved surface area of cylinder.
Let r be the radius of the cylinder. Then ,
=> 3168 = 2 x (22/7) x r x 42
=> (3168 x 7 )/(2 x 22 x 42) = h
=> h = 12 cm. (Ans.)
