Answer:
25,120 sq. metres
Step-by-step explanation:
Find the diagram attached
Lateral surface area = πrl
r is the radius
l is the slant height
Given
r = 160/2 = 80m
l = √r²+h²
l = √80²+60²
l = √6400+3600
l = √10,000
l = 100cm
Lateral surface area = 3.14 * 80 * 100
Lateral surface area = 25,120 sq. metres
