Cone Calculator

An easy to use online calculator to calculate the lateral surface area and the volume of a right cone given any two of its dimensions: radius r, height h and slant height s.
Formulas of Area and Volume of a Cone Used in this CalculatorLet r be the radius of the base and h the height of the cone as shown in the above diagram. The area of the surface and volume of the cone are given by:Base surface area \( B_a= \pi r^2 \) (area of the circular base) Lateral surface area: \( L_a = \pi r \sqrt{r^2+h^2} \) (area of lateral surface) Total surface area \( T_a= \pi r^2 + \pi r \sqrt{r^2+h^2} \) Volume \( = \dfrac{1}{3} \pi r^2 h \) Slant height s \( = \sqrt{r^2+h^2} \) (length from the apex of the cone to a point on the circle making the base) Height h \( = \sqrt{h^2r^2} \) Radius r \( = \sqrt{h^2h^2} \) Use the Calculator to Find the Area and Volume of the Cone Given its Height h and Radius r
Enter the radius r of the base and height h of the cone as positive real numbers and press "Calculate Area and Volume". The outputs are the lateral surface area \( L_a \) , the base area \( B_a \), the total area \( T_a \), the volume of the cone V and the slant height s.
Use the Calculator to Find the Area and the Volume of the Cone Given its Radius r and Slant Height s
Enter the radius r of the base and the slant height s of the cone as positive real numbers such that s is greater than r and then press "Calculate Area and Volume". The outputs are the lateral surface area \( L_a \) , the base area \( B_a \), the total area \( T_a \), the volume of the cone V and the height h.
