Answer:
The population of Hawks and other species would likely start to edge off.
Step-by-step explanation:
Commonly, a Food Chain is dependent on all the parts of it sataying at a perfect point. If the food that the Snakes eat starts to run out, more of them will die off. With less Snakes, the Hawks will then have less food, and that continues throughout the chain. The same thing would happen if there was too much food, except instead of the populations of species dying off, the Snake population would spike.
The area for semi circle is: (pi)(r^2)/2
A= 3.142 x (8.2)^2 / 2
A= 110.8 cm^2
