you have some options:

 ISegmentCollection segmentCollection = new PolygonClass(); segmentCollection.SetCircle(point, 10); IGeometry circle = segmentCollection as IGeometry;

or you can cast the point to ITopologicalOperator and use buffer

or you can rotate a vector from a center point

or use EllipticArcClass

and so on..
