Question 120533
Formula for the surface area of a cylinder is:
{{{A=2(pi)r^2+2(pi)rh}}}
You are given r and h, so just plug and chug:
{{{A=2(pi)(3^2)+2(pi)(3)(8)}}}
Simplifying:
{{{A=2(pi)(9)+2(pi)(24)}}}
{{{A=18(pi)+48(pi)}}}
{{{A=66(pi)}}}
You can plug that into your calculator to get a numerical answer. Don't forget to round it off.
