Do you mean to find the total surface area?

anonymous · Answer

i said 96π

@GoldPhenoix i guess so. it's whatever's in the question

ashleyisakitty · Answer

You are correct Lana! Good job.

ashleyisakitty · Answer

I got 301, which is also your answer :~)

anonymous · Answer

thanks @Ashleyisakitty and @GoldPhenoix i think it's the height. i've already tried it to make it the slant height but i got it wrong.

goldphenoix · Answer

Actually to find the surface area, you must use the slant height. http://www.web-formulas.com/Math_Formulas/Geometry_Surface_of_Cone.aspx

goldphenoix · Answer

To find the surface area of any cone, you must use the formula: $$πr^2 + πrl$$
l= slant height. So if you plug it in, it would be $$\Pi6^2 + \Pi6 x8$$
Simplify:
$$36\Pi + 48\Pi = 84\pi$$
$$84\Pi = 263.89$$
