See the API docs for every endpoint and the input schema.
FAQ
How do I calculate the volume of a cylinder?+
Multiply the area of the circular base by the height: V = πr²h. A cylinder with radius 3 and height 10 holds about 282.74 cubic units.
How is the surface area of a cylinder found?+
Add the two circular ends to the curved side: 2πr² + 2πrh, which factors to 2πr(r + h). That is the total surface area for a closed cylinder.
How do I get liters or gallons from the volume?+
Keep your inputs in one unit and convert the cubic result. For example, a volume in cubic centimeters divided by 1,000 gives liters, and cubic feet times about 7.48 gives US gallons.
