$\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \textit{we also know that } \begin{cases} \stackrel{f(x)}{y}=6\\ ~~ x=4 \end{cases}\implies 6=\cfrac{k}{4}\implies 24=k~\hfill \boxed{y=\cfrac{24}{x}} \\\\\\ \textit{when x = 8, what is \underline{y}?}\qquad \qquad y=\cfrac{24}{8}\implies y=3$

What is the total surface area of the code?

Ksju [112]

<h2>Hello!</h2>

The answer is: None of the options.

The correct answer is: $703.69cm^{2}$

The total surface area of the cone is equal to:

$TotalArea=BaseArea+LateralArea$

Calculations:

tex]BaseArea=\pi*r^{2}=\pi*7^{2}=153.94cm^{2}[/tex]

$LateralArea=BasePerimeter*SlantHeight/2\\BasePerimeter=2*\pi*r=2*\pi*7=43.98cm\\SlantHeight=\sqrt{height^{2}+radius^{2} }=\sqrt{576+49}=\sqrt{625}=25$
