Best ResponseYou've already chosen the best response.0im using this site http://www.webformulas.com/Math_Formulas/Geometry_Surface_of_Cone.aspx but got the wrong answer and kind of confused how to put it all in the formula..

Best ResponseYou've already chosen the best response.0so \[3.14*7\sqrt{7^{2}}+24^{2} + 3.14*7^2 =\] 16909.214

Best ResponseYou've already chosen the best response.1ohh hmmm your choices are in \(\huge \pi\) terms thus... you need to keep the \(\huge \pi\) without multiplying it

Best ResponseYou've already chosen the best response.0so how do i do that?

Best ResponseYou've already chosen the best response.1well.. just don't multiply the \(\pi\) and keep it as is, as a variable per se

Best ResponseYou've already chosen the best response.1hmmm have a typo there one sec \(\bf \textit{total surface area of a cone}=\pi r\sqrt{r^2+h^2}+\pi r^2\qquad \begin{cases} r=radius\\ h=height \end{cases} \\ \quad \\ \pi r\sqrt{r^2+h^2}+\pi r^2\implies \pi r(\sqrt{r^2+h^2}+r)\impliedby \textit{common factor} \\ \quad \\ \begin{cases} r=7\\ h=24 \end{cases}\implies \pi \cdot 7(\sqrt{7^2+24^2}+7)\implies \square ?\pi \)

Best ResponseYou've already chosen the best response.1so in \(\pi\) terms is \(\large 224\pi\)
