How many faces does a cylinder have in 3D?

Published in Geometry 1 min read

A cylinder in 3D has 3 faces.

Here's a breakdown:

  • Two Circular Faces: These are the flat, circular ends of the cylinder.
  • One Curved Face: This is the curved surface connecting the two circular faces. Imagine unrolling a can of soup; this surface would become a rectangle.

Therefore, the total number of faces is 2 (circular) + 1 (curved) = 3.

Face Type Number Shape
Circular (Flat) 2 Circle
Curved 1 Rectangular

A cylinder has no vertices (corners) and two edges (the circles where the curved surface meets the flat faces).
