Calculation procedure

Formulas

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
$$ d = 2 \cdot r $$
$$ \pi \doteq 3.14 $$
