Question
Find the lateral area of the figure. Round your answer to the nearest hundredth.
Hint:
The Formula for lateral surface area of the cone is 
where l is the slant height and r is the radius of the circular base of the cone.
The correct answer is:
Given diameter of base of cone = 17 km the radius of base of cone r = 8.5 km
The slant height of cone l = 23.6 km
Therefore, lateral surface area of cone is .
