Truncated Cone Calculator
Calculations in a truncated right circular cone (conical frustum). A truncated cone is a cone with the tip straight cut off. The base is the larger circle, the top surface is the smaller circle. The slant height is the shortest distance between the two circles, the lateral surface is the surface without the circles. Enter radiuses and height and choose the number of decimal places. Then click Calculate. For the calculation of general truncated cones see frustum .

Formulas:
s = √ (R - r)² + h²
L = ( R + r ) * π * s
A = L + πr² + πR²
V = h * π / 3 * (R² + Rr + r²)
pi:
π = 3.141592653589793...

Radiuses, height and slant height have the same unit (e.g. meter), surfaces have this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter). A/V has this unit ^{-1} .
