Question

am i right?
What is the total area of this cone?

Answer 1

Do you mean to find the total surface area?

Answer 2

i said 96π

Answer 3

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

Answer 4

You are correct Lana! Good job.

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

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:
\[36\Pi + 48\Pi = 84\pi\]
\[84\Pi = 263.89\]
