1. 
   Using the diameter of the circle as side construct the square ABCD, join the diagonals to intersect at O. centre at O and the given radius inscribe the circle in the square ABCD.
   
2. 
   Draw the square ABCD in isometric as shown.
   
3. 
   Bisect lines DC and CB at E and F respectively.
   
4. 
   Join the diagonal BD
   
5. 
   Centre at C1 and C2 radius C1E and C1F draw the arcs.
   
6. 
   Centre at A and C radius AE and AF draw arc to complete the isometric circle.
