Lisa = 28 yrs

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.
