Solution :
Dimensions of the cylinder :
radius ( r ) = 5 cm,
Let the height = h cm
Curved surface area ( A ) = 440 cm²
=> 2πrh = 440
=> 2×(22/7)×5×h = 440
=> h = ( 440×7 )/( 2 × 22 × 5 )
=> h = 14 cm

C. S. A of cylinder =2πrh
therefore,
2x22/7×5×h =440
h= 440×7/2×22×5
h=14 cm
therefore,
2x22/7×5×h =440
h= 440×7/2×22×5
h=14 cm
