Question

the curved surface area of a cylinder is 660cm2 radius is 5 find its height

Answer 1

Radius of cylinder = 5 cm

Curved surface Area = 660

=> 2 pi R h = 660

=> 2 × 22 × 5 × h / 7 = 660

=> 220h = 660 × 7

=> h = 3 × 7

=> h = 21

Height of cylinder = 21 cm

Answer 2

Radius of cylinder = 5 cm

Curved surface Area = 660

=> 2 pi R h = 660

=> 2 × 22 × 5 × h / 7 = 660

=> 220h = 660 × 7

=> h = 3 × 7

=> h = 21

Height of cylinder = 21 cm
