A Frustum is a three-dimensional geometric shape which resembles a cone with the top cut off.
The top and base diameters are parallel and on the centre of axis.
Calculations can be saved to a table by clicking the "Add to Table" button (the table appears the first time the button is clicked)
There is also the option to create a PDF document
Slope Height (s) = √((r2 - r1)2+h2)
Surface area of top (T) = πr12
Surface area of base (B) = πr22
Lateral surface area (L) = π x (r1 + r2) x s
Total area = T + B + L
Volume = (1/3) x π x h x (r12 + r22 + (r1 * r2))
