Volume and surface area of a cone

A right circular cone is formed by a circular base and a lateral surface.
The height of a cone is perpendicular to its base.

cone

volume

$$ V = \frac{1}{3} \pi r^2 h$$

surface area

$$ \begin{aligned} A &= A_b + A_{l} \\ \\ A &= \pi r(r + s) \end{aligned} $$

base area

$$ A_b =\pi r^2 $$

lateral area

$$ A_{l} = \pi r s $$

slant height

$$ s = \sqrt{h^2 + r^2} $$

circumference

$$ C = 2 \cdot \pi r $$

diameter

$$ d = 2 \cdot r $$

$$ \pi \doteq 3.14 $$
