This Surface Area of a Cone Frustum calculator 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:
- Surface Area: cone surface area based on cone height and cone base radius
- Volume: cone volume based on cone height and cone base radius
- Mass: cone mass or weight as a function of the volume and mean density
- Frustum Surface Area: cone frustum surface area based on the two heights and two radii
- Frustum Volume: cone frustum volume based on the two heights and two radii
- Frustum Mass: cone frustum weight or mass based on the cone frustum volume and mean density
- Shell Volume: cone shell volume a.k.a. hollow cone volume
- Shell Mass: cone shell mass or weight a.k.a. hollow cone mass.
- Compute the total surface are of the frustum of a cone: This includes the top and bottom surfaces.
- Compute the lateral surface area (using L) of the frustum of a cone.
