If the net was folded into a cylinder, the length of the rentangle would be the circumference of the circle since it wraps around it.
C = 2pi*r
So 2pi*3 = 6pi
Then multiply by the height to get 84pi
Then the area of a circle is pi*r^2
We have two circles so 2 * pi * 3^2 = 18pi
Add to get 84pi + 18pi = 102pi.
The answer is b or the second choice available
For the greater part of man's opportunity on earth, populaces were little, scattered, and subordinate after chasing and assembling. Those infectious diseases that influenced people were either the consequence of unplanned contamination by zoonoses or lethargic contaminations that maybe had developed with people from their primate precursors. It was just because of the rural upheaval 6,000 to 8,000 years back and the resulting development of inactive populaces sufficiently substantial to help microorganisms particularly subordinate upon human has that epidemics and pandemics seem to have moved toward becoming piece of man's life (Cockburn 1963)
