What is the surface area of the cone?
goblinko [34]

Answer: C

Step-by-step explanation:

To find the surface area of a cone, you use the formula A=\pi r(r+\sqrt{h^2+r^2} ). Since we are already given the height and radius, all we have to do is plug in the values and solve.

A=9\pi (9+\sqrt{41^2+9^2} )       [solve inside of square root]

A=9\pi (9+\sqrt{1762} )             [parenthesis]

A=9\pi (50.976 )                   [multiply]

A=458

Therefore, the closest answer is C.
