Is the formula given for the slant height ?

anonymous · Answer

here it is! Sorry!

perl · Answer

We can plug in S and r into the formula

anonymous · Answer

Yeah because those are given in the problem but aren't I suppose to solve for the variable? Or ... if I do that am I already doing that?

perl · Answer

Here we don't have to solve. just plug in :)
$$ \large l=\frac{S - \pi r^2 }{\pi} $$

anonymous · Answer

Oh okay. I'll do it now.

I got 275 ft
