## Recommended Answers

Jump to PostIn cylinder class,

`getRadius()`

,`calcArea()`

are of circle class, and you are using them in cylinder class, you might want to write separate functions for both of these classes. If you see, you will realize that when`getRadius()`

is called in Cylinder class, it has value 0.And never use …

Jump to PostYou can code setHeight() such that it takes the height and radius, from the circle part.

`cylinder.setHeight(h, r)`

.
