If your circle is centered at (0,0), you can use a polar function. For example r(t)=5 will plot a circle with radius 5. If you want to calculate the area of the whole circle you can use *Calc|Area* with From=0 and To=2pi. Likewise if you want to calculate the whole perimeter you can use *Calc|Length of path* with From=0 and to=2pi.

I drew a circle through "relation". Is that the problem?

Even when drawing through "parametric function" I am having issues.

Any help would be greatly appreciated! (especially when drawing through "relation" as I find that more simple).]]>
