Answer:
H. 163.3
Step-by-step explanation:
The formula for the surface area of a cone is πrl(area of the side) + π
(area of the base), where l is the slant height and r is the radius. We know that the radius is 4 and the slant height is 9, so we plug it into the equation to get π(4)(9) + 
= 36π+16π = 52π which rounds to 163.3.
