A circle has an area of 3.14 cm^2 . What is its radius?

1cm
2cm
1/2cm
cant be detemined

The radius of the circle is 1 cm, if the circle has an area of 3.14 .

Step-by-step explanation:

         The given is,

                  Area of the circle is 3.14 ,

Step:1

        The formula for Area of circle,

                    A = π....................(1)

       where,

                   π - 3.14

                    r -  Radius of circle

Step:2

         From the given,

               Area, A = 3.14

        Eqn (1) becomes,

                  3.14 = 3.14 ×                (∵ π = 3.14 )

                      =

                      = 1

                    r =

                      = 1

                    r = 1 cm

           Radius of circle, r = 1 cm

Result:

      Thus the radius of the circle is 1 cm, if the area of circle is 3.14 .

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

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 !
