Lateral and Total Area of Pyramid and Cone

Applied Mathematics — Second Secondary

Lateral and Total Area of Pyramid and Cone

Lesson summary

Lesson summary

  • Lateral area of a regular pyramid = ½ × perimeter of the base × slant height.
  • Total area = lateral area + area of the base.
  • Lateral area of a right circular cone = π r l, and total area = π r (r + l).
  • The slant height satisfies l² = h² + m² in a regular pyramid, and l² = r² + h² in a right circular cone.
