Find the missing measure for a right circular cone given the following information. Find L.A. if r = 6 and h = 8 48 60 96
svetlana [45]
\bf \textit{lateral area of a cone}\\\\
LA=\pi r\sqrt{r^2+h^2}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=6\\
h=8
\end{cases}\implies LA=\pi(6)\sqrt{6^2+8^2}
