Brainliest answer please

Answer 2

hello users ....

We know that:
Curved surface area of cylinder = 2πrh Or πdh

where, r is radius and d is the diameter of base of cylinder.

Solution:-
According to given:
Diameter of base of cylinder = 28 cm 
And
C.S.Area of cylinder = 1056 cm²

=> πdh = 1056 cm²

=> 28×h×22/7 = 1056 

=> 22×28×h = 1056×7

=> 616 h = 7392

=> h = 7392 / 616 = 12 cm Answer 

@ hope it helps :)
