101 block circle in Minecraft (radius 50)

A 101-block-wide circle takes 284 blocks for a 1-block outline and 8,021 to fill it. Go around each quarter in runs of 15·5·3·3·2·2·2·2·2·1·1·2·1·1·1·1·1·1·2·1·1·2·2·2·2·2·3·3·5·15. The centre is a single block, because 101 is odd.

How to build it

  1. Mark the centre block. Count 50 blocks out from the centre block in all four directions and mark those four points.
  2. Place the four flat edges of 15. Centre each flat edge on one of the four points: 7 blocks either side of it.
  3. Fill each corner with 5·3·3·2·2·2·2·2·1·1·2·1·1·1·1·1·1·2·1·1·2·2·2·2·2·3·3·5. After each run, step one block diagonally inward and place the next run. Do the same in all four corners.
  4. Repeat for each layer. A straight wall is the same ring on every layer (a 5-high wall takes 1,420 blocks). A dome or sphere shrinks the ring as it goes up.
All 101 rows, north to south

Each row lists its runs of blocks from west to east; "2-2" means 2 blocks, a gap, then 2 blocks.

Questions

How many blocks is a 101 block circle?

284 blocks for a 1-block outline with diagonal steps, 400 for an outline with no diagonal gaps, and 8,021 for a filled disc.

Should I build 101 or 100?

101 is odd, so the circle has one centre block: doors, beacons and pillars line up with the middle. 100 has a 2×2 centre instead.

How many blocks for a 101 sphere or dome?

A hollow 101 block sphere with a 1-block shell takes 26,342 blocks; a hollow 101 dome (51 layers, open at the bottom) takes 13,253. Plan them layer by layer in the sphere generator or the dome generator.

Thin or thick outline?

A thin outline (284 blocks) steps diagonally, so mobs and water can slip through the corners. A thick outline (400 blocks) adds a block at every step, which makes a sealed wall.
