\(a^2+b^2=c^2\) where c = 17 ft and a = r dw:1342800106700:dw= 8 ft

\[\text{Volume} = \frac{\pi r^2 h}{3}\] \[\text{Surface Area} = \pi r s + (\text{Area}_{\text{circle}}) = \pi r s + \pi r^2\] s = c = 17 ft

You should now be able to find either volume or surface area @NyKole ^_^ Make sense?

Maybe this will make it more interesting then... :P http://media.giantbomb.com/uploads/0/6087/1089291conehead_zombie_large.jpg

\(\text{Surface Area} = \pi (8 \ ft)(17 \ ft) + \pi (8 \ ft)^2\) \(\text{Surface Area} = 136\pi \ ft^2 + 64\pi \ ft^2\) \(\text{Surface Area} = 200\pi \ ft^2 \approx 628 \ ft^2\) Correct! Good job (see how the units work btw? foot * foot = feet squared)

The precise answer would be "200\(\pi\) ft\(^2\)" :) That's what my boss would want if I was engineering something like this. Any contractor making the item can use a little calculator onsite to figure out how accurate they want to get.
