Answer 2

Answer:

Given that:

curved surface area of cylinder = 1760 cm²

&

volume of cylinder = 12320 cm³

we have to find:

height of cylinder= ?.

solution:-

we know that ;

curved surface area of cylinder = 2πrh

&

volume of cylinder = πr²h

here,

according to given;

C.S.Area = 1760

=> 2πrh = 1760

=> πrh = 1760 / 2 = 880

and

volume = 12320

=> πr²h = 12320

=> πrh × r = 12320

=> 880 × r = 12320

=> r = 12320 / 880

=> r = 14 cm

now,

putting the value of 'r' in

2πrh = 1760

=> 2π × 14 × h = 1760

=> h = 1760 / 28π

=> h = ( 1760 / 28 ) ×( 7/22 )

=> h = 12320 / 616

=> h = 20 cm Answer
