Answer 1

The curved surface area of a cylinder is 1760 cm² and its base radius is 14 cm. The height of the cylinder is 20 cm.

Explanation:

Curved surface area of the cylinder `= 2pi"rh"`

`=2xx22/7xx14xx"h"`

`=> "h" = 1760/88  "cm"`

`=> "h" = 20  "cm"` 

Height, the height of the cylinder is 20 cm.
