Question

1.


Look at the cone above. If R=6 cm and H=8 cm, what is the surface area of the cone?
Surface Area of a Cone = r(l + r) where l is the slant height

Answer 1

Well this is a right cylinder cone.
Therefor the area is equal to

\[\pi*r(r+\sqrt{h^2+r^2}))\]

Answer 2

\[6\pi(6+\sqrt{64+36})\]

Answer 3

\[6\pi(6+\sqrt{100})\]\[6\pi(6+10)\]\[16*6*\pi = 96\pi\]
