What shape does the development of a pyramid's lateral surface take?

  • A.an annulus between two concentric arcs
  • B.a fan of triangles about the apex
  • C.a rectangle of the base perimeter
  • D.a sector of a circle struck from the apex

Answer: B

Each lateral face is a triangle whose true sides must be found, and the faces are laid out side by side about the common apex. A cone's development is a continuous sector because its generators are infinitely numerous rather than four or six.
