Four hundred meter of fencing are required to enclose a square field .what area can be enclosed by the same length of fencing if the enclosure is circular?

Answer 1

#= 40000/pi m^2#
#~~12732.395 m^2#

The length of the fencing is #400m#. So we must find the area of a circle with circumference# ~~ 400m#. Note that due to the transcendental nature of #pi#, the exact value cannot be calculated. #2pir = 400# #implies r = 200/pi#
Area of a circle equals #pir^2# #= pi(200/pi)^2# #= pi(40000)/pi^2# #= 40000/pi m^2# #~~12732.395 m^2#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
