Calculations in a flat end cylinder or double cylindrical wedge. This is the matching counterpart to two equivalent cylindrical wedges with the angle Φ=90°, which touch at their straight edges. Together with those two, it forms a full cylinder. Radius and height are those of the complete zylinder, the length is that of the oblique side faces. Enter exactly two of the three values of radius, height and length and choose the number of decimal places. Then click Calculate. Angles are calculated and displayed in degrees, here you can convert angle units.
l² = r² + h²
d = 2 r
α = arccos( ( 2 * l² - 4 * r² ) / (2 * l²) )
L = ( 2π - 4 ) * h * r
A = L + π r l + π r²
V = ( π - 4/3 ) * r² * h
Radius, height and lengths have the same unit (e.g. meter), the areas 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. The lateral surface is the curved part of the surface area.
