A farmer has a fence that encloses a square plot with an area of 100 square meters. If the farmer uses this fence to enclose a circular flower garden, what will the area of the garden be? (Use π = 3.14. Round your answer to two decimal places.)

Question

answer in meters squared

anonymous · Answer

p = 2*pi*r

100 meters divide by pi then divide by 2 is
50/pi meter  (radius)
A= Pi*r^2
(50/pi)^2 * pi     =   2500/pi  square meter
in real number: 795.77 square meter

answer was wrong

so the length of the fence is 4*sqrt(100)=40

*facepalm   my fault completely.
100 square square garden is equal to 10 meter per side.
then the parameter is 40 meter.
using 40/2/3.14=6.394 = r
6.3694*3.14*6.3694 = 127.39 square meter.
