How will the area of the circle change if it is dilated by a scale factor of 1/2

 The area of the dilated circle will be one-forth of the area of the original circle.

Step-by-step explanation:  We are given to find the change in area of a circle if it is dilated by a scale factor of half.

Let r represents the RADIUS and A represents the AREA of the circle before dilation.

And, r' represents the radius and A' represents the AREA of the circle after dilation.

So, we get

In case of a circle, scale factor is the ratio of the radius of the dilated circle to the radius of the original circle.

That is,

Therefore, the area of the dilated circle will be

Thus, the area of the dilated circle will be one-forth of the area of the original circle.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

the answer would be 44.79
