@Damini2004, You should add your calculator in alphabetical order in main index.html file of the project.

[Nihal4777]

@Damini2004 UI needs to be improved little bit. Also, you have specified that you will provide diagram?

[Nihal4777]

@Damini2004 On small screens, there is overflow.

[Damini2004]

Yes it will overflow because the radius is increased then it not possible to visible the bigger circle. so we can provide diagram of inner circle rather than outer circle. Are you ok with it.

[Rakesh9100]

Where is the proper diagram, just white circle is visible. Also, that is hiding the result, pls fix @Damini2004

[Rakesh9100]
