Area and perimeters
Circumference of a circle
Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle P = 2 \pi r}
Area of a circle
Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle A = \pi r^2}
Volume and surface area
Surface area of a sphere

Volume of a sphere
Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle v(r) = \frac{4}{3}\pi r^3}
where r is the radius of a sphere
Volume of a cone
Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle v(r) = \frac{1}{3}\pi r^2 h}
where r is the radius of the base, and h is the height of a cone
Volume of a cylinder
This only applies to a right cylinder.
