Question

The curved surface area of a cylinder is 1980 cm and radius of its base is 15 cm find height of cyclinder

Answer 1

2πrh=1980 h=1980*7/2*22*15 h=21cm

Answer 2

Hope this will help u......

Answer:

Step-by-step explanation:

Curved surface area of cylinder =2πrh

1980=2*22/7 *15*h

1980=44*15/7*h

1980*7=44*15*h

13860=660*h

13860/660=h

h=21

So the height of the cylinder is 21cm.....
