Sealmount Sphere and dome blueprints 21 × 21 Minecraft 21×21 Sphere and Dome: Layer-by-Layer Blueprint
A hollow sphere 21 blocks across, 1 block thick, takes 1,082 blocks in 21 layers. The dome is its top 11 layers: 569 blocks. A solid sphere takes 4,945.

Layers (sphere / dome) 21 / 11
Open this sphere in the generator Open the dome
There you can change the shell thickness, make it solid or oval, or pick another height, then check off each row as you build.
Charts show the hollow sphere with a shell 1 block thick, in full blocks. The dome is its top half; the dome's bottom layer has the same outer edge as the Circle generator's circle of the same diameter. Layer 1 is the bottom. Rows run north to south and columns west to east, both counted from 1. Every “skip” is counted from the west edge. Rows without blocks are left out. How the calculations work
