anonymous · Answer

surface area=pi r(r+l)
l is the slant height

anonymous · Answer

so it would be 89=3.14 times radius ^2 ?

anonymous · Answer

yeap

anonymous · Answer

so i would divide 89 by 3.14 then what?

amistre64 · Answer

we appear to be looking for a height in order to apply the pythag thrm to this

anonymous · Answer

so i have to use the theorum?

anonymous · Answer

cool did youdo that?

anonymous · Answer

Since the height of the cone is not given, u have to use the formula. Pythagoras theorem isnot applicable here

anonymous · Answer

o ok but i keep getting the wrong answer

amistre64 · Answer

wolfram did it; i just typed in the information :)
