Try it: Round bistro table with four stools

A café table layout you can drop straight into a floor plan, plus a plant pot in the corner. Only CIRCLE and DONUT are used.

1. Type C, Enter, 0,0, Enter, then radius 400 and Enter. That is a Ø800 table top.
2. Draw the stools with radius 200, one at a time: C 650,0 200 / C -650,0 200 / C 0,650 200 / C 0,-650 200 (press Enter after each value).
3. Add a plant pot: type DONUT 150 220, press Enter, then type 1100,800 and press Enter.
4. Type ZE to see the whole set. Each stool clears the table edge by 50 mm, enough to tuck it under.

Challenge: Delete three stools and run ARRAYPOLAR 6 on the last one around 0,0 to make a six-seat table. See ARRAY.
