Make sure you make radius as private in the Class definition.

Then,

create circle$1(10),$ circle$2(20)$ and circle$3$

circle$3$ should have radius $1.$

$1)$Write a function as part of class Circle that will return the radius. call it getRadius. Then print radius of circle$3.$

$2)$ Change circle$3$ radius to be $2$ times radius of circle$2.$ How do you do that using setRadius and getRadius?
