What are the lateral area and the surface of the cone shown below?

Ierofanga [76]

$\bf \textit{lateral surface area of a cone}\\\\
LA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}\implies LA=\pi (11)(24)
\\\\\\
\boxed{LA=264\pi }\\\\
-------------------------------$

$\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}
\\\\\\
SA=\pi (11)(24)+\pi (11)^2\implies SA=264\pi +121\pi 
\\\\\\
\boxed{SA=385\pi }$

You can type those equations into the desmos graphing calculator online! find the feasible region (where all the colors overlap) and find the vertices then fill them into the objective function! if you have any more questions then let me know!!

Thanks. If you could include the work that would be awesome.

Phoenix [80]

Answer:

Step-by-step explanation:

a) (2,350),(5,530)

b) (530-350)/(5-2)=60

c) y=60x+b, using point (2,350)

350=60(2)+b

b=230

w=60t+230

c) w(7)=60(7)+230

w(7)=$650
