A circular garden has an area of 25π m2
If the .
radius is increased by two meters, and fencing is
sold only in one meter sections, how much fencing
is needed to keep out the rabbits?

    114

    how did you get 114???

    The radius of the garden before change=5(since 5x5=25). 5+2=7, which is the new radius of the garden.
    To get the amount of fencing needed, you first need to find the diameter and the resulting circumference.
    D=2r, r=7, therefore D=14. C=D¥ð, so the circumference is 14¥ð.
    That's about 43.9 meters.
    Therefore you need 44 meters of fences, which is 44 fences.
