To construct the frustum, you need to find x, y and the central angle t. The formulas for these perimeters may be found in
How to construct a frustum?
. Here you may use the calculator below to calculate these parameters.
How to use the calculator
Enter radius r (radius at top), radius R (radius at bottom) with r < R and height h of the frustum as positive real numbers and press "calculate". The outputs are the lateral surface area, the total surface area (including the base and bottom), the volume of the frustum and parameters x, y and angle t for the construction of a frustrum given r, R and h.
