Base of a Cone

 

formulas that use Height of a Cone

\(\large{ h = 3\; \frac{V}{\pi \;r^2} }\)   

Where:

\(\large{ h }\) = height

\(\large{ V }\) = volume

\(\large{ r }\) = radius

 

formulas that use Slant Height of a Cone

\(\large{ s = \sqrt {r^2+h^2} }\)   

Where:

\(\large{ s }\) = slant height

\(\large{ A }\) = area

\(\large{ r }\) = radius

\(\large{ h }\) = height

 

formulas that use Surface Area of a Cone

\(\large{ A_s = \pi\; r\; \left( r + \sqrt { h^2 + r^2 } \right) }\)   

Where:

\(\large{ A_s }\) = surface area

\(\large{ \pi }\) = Pi

\(\large{ \sqrt a }\) = square root

\(\large{ r }\) = radius

\(\large{ h }\) = height

 

formulas that use Volume of a Cone

\(\large{ V = \frac {1}{3}\; \pi\; r^2 }\)   
\(\large{ V = \frac {1}{3} \;b\;h }\)   

Where:

\(\large{ V }\) = volume

\(\large{ r }\) = radius

\(\large{ b }\) = base area

\(\large{ h }\) = height

\(\large{ \pi }\) = Pi
