App Description

Truncated straight cone calculation

\(C=πl(R+r)\)

\(F= \frac {π}{2} [l(D+d)+ \frac {1}{2} (D^+d^2)]\)

\(V= \frac {πh}{3} (R^2+r^2+Rr)\)

\(V= \frac {πh}{12} (D^2+d^2+Dd)\)

h - high

D——lower bottom diameter

D——upper diameter

R——lower radius

R——the radius of the upper base

l - bus length

Input data:

H—high: 4

D—lower bottom diameter: 8
