Question 264827
Mananth did this correctly im just going to make it easier to read.
surface area of a cylinder = {{{2(pi)r^2+2(pi)r*h}}} {{{(pi)=3.1416}}}
{{{2(pi)r^2+2(pi)r*x=408}}} 
{{{2(pi)5^2+2(pi)5*x=408}}}
{{{2(pi)5^2-2(pi)5^2+2(pi)5*x=408-2(pi)5^2}}}
{{{(2(pi)5*x)/2(pi)5=(408-2(pi)5^2)/2(pi)5}}}
{{{x=(408-2(pi)5^2)/2(pi)5}}}
{{{x=(408-2(25)(pi))/10(pi)}}}
{{{x=(408-50(pi))/10(pi)}}}
{{{x=(408-50(3.1416))/10(3.1416)}}}
{{{x=(408-157.079)/31.416}}}
{{{x=(250.921)/31.416}}}
{{{x=7.987}}} round to nearest 100th
{{{x=7.99}}}inches
