Draw circle on map and find centre and radius

Discussion created by lukestewart-esriuk-esridist on Aug 24, 2011
I am quite new to ArcObjects and am building am ArcGIS Add-In using .Net with c#. I have a new button and what I want to do is when pressed draw a circle on the map and then return the radius and centre of the drawn circle. I can not find out how to do this??
Would it be possible to draw a circle using the circle tool from the draw tool bar and then get the radius and centre from this?

Thank you,
