Formula
l = √(r²+h²); V = (1/3)πr²h; Lateral = πrl; Total = πr(r+l)
- Cone Calculator calculates its result from Rate (decimal), Height, Pir, Pirl. It uses the formula l = √(r²+h²); V = (1/3)πr²h; Lateral = πrl; Total = πr(r+l). Change any input to recalculate the result instantly.
- The main inputs are Base Radius, Height. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Cone
