Trouble finding radius size p2.js

Hello, I wanted to know if there is a way to figure out the radius size of a p2Circle or p2Box on an entity so that I have a visual reference. If I can find this out I can do a little less coding for a bug. Is there any way to visually see the size of a p2Box or p2Circle?

Thanks,
Chhes

Temporary use a sphere or cube as a reference on size and delete afterwards

I think there is also a debug option on the p2 engine where it renders the collision too at run time
