Cone - Frustum Surface Area 2

vCalc Reviewed
SA=π(a+b)L
(a)Radius of the top
(b)Radius of the bottom
(L)Length of the sloped side

This Surface Area of a Cone Frustum calculator/attachments/36a660d1-14cc-11e3-8615-bc764e049c3d/ConeFrustumSurfaceArea2-illustration.png computes the lateral surface area of a right circular cone with a frustum defined by base radius (a) and top radius (b) and the side wall length (L) in between.

INSTRUCTIONS: Choose your preferred length units and enter the following:

  • (a) Top radius
  • (b) Bottom radius
  • (L) Length of the side wall

Surface Area:  The calculator returns the surface area in square meters.  However, this can be automatically converted to other area units via the pull-down menu.

Cone Calculators

  1. Surface Area:  cone surface area based on cone height and cone base radius
  2. Volume: cone volume based on cone height and cone base radius
  3. Mass: cone mass or weight as a function of the volume and mean density
  4. Frustum Surface Area: cone frustum surface area based on the two heights and two radii
  5. Frustum Volume: cone frustum volume based on the two heights and two radii 
  6. Frustum Mass: cone frustum weight or mass based on the cone frustum volume and mean density
  7. Shell Volume: cone shell volume a.k.a. hollow cone volume
  8. Shell Mass: cone shell mass or weight a.k.a. hollow cone mass.
  9. Compute the total surface are of the frustum of a cone:  This includes the top and bottom surfaces.
  10. Compute the lateral surface area (using L) of the frustum of a cone.
