An old fence used to enclose a circular lot is to be recycled to fence a square lot.
If the radius of the circular lot is 5 meters, how long should the edge of the square lot be?
:
Let s = side of the square
then
4s = the perimeter of the square
:
the perimeter of the square lot = the circumference of the circular lot
:
4s = 2%2Api%2A5
:
s = %282%2Api%2A5%29%2F4
s = 7.854 meters
