Minecraft ores follow a triangular distribution pattern, with ores less common at their minimum and maximum Y-levels and most common at the midpoint between the two. There are exceptions — some ores like Iron have high distribution levels at higher Y-levels in mountainous biomes — but that's a solid rule of thumb to follow.

Now we also know that the arc length of the sector is the same as the circumference of the base of the cone because that's what's used to form the cone and we know the radius of the base of the cone, so we can work that out. This length here is two times 𝜋 times the radius; that's two times 𝜋 times fifteen, which is equal to thirty ...
