Fórmula
Formulas: Volume V = (1/3)πr²h, Slant height l = √(r² + h²), Lateral area S_lat = πrl, Total area S_tot = πr(r + l).
Perguntas Frequentes
How do you calculate the volume of a cone?
The volume is one-third of a cylinder with the same base and height: V = (1/3)πr²h.
What is the slant height?
The slant height is the distance from the apex to any point on the base circle: l = √(r² + h²).
How do you find the lateral surface area of a cone?
Multiply π by the radius and the slant height: S_lat = πrl.
What is the total surface area?
Add the lateral area and the base area: S_tot = πrl + πr² = πr(r + l).
