Formula: Right Circular Cone Area Side length Pi
$$A ~=~ \pi \, \class{red}{r} \, (\class{red}{r} + s)$$
$$A ~=~ \pi \, \class{red}{r} \, (\class{red}{r} + s)$$
$$s ~=~ \frac{A}{\pi \, \class{red}{r}} - \class{red}{r}$$
Area
$$ A $$ Unit $$ \mathrm{m}^2 $$
The total area (surface) of a right circular cone.
Side length
$$ s $$ Unit $$ \mathrm{m} $$
The distance from the base to the vertex of the cone.
Radius
$$ \class{red}{r} $$ Unit $$ \mathrm{m} $$
Radius of the circular base of the cone.
Pi
$$ \pi $$ Unit $$ - $$
Pi is a mathematical constant and has the value \( \pi ~=~ 3.1415926... \)
