Question 673277
Suppose you have 100 ft. of fencing to build a kennel.
 What is the largest square kennel you can build? 
Each side of the square: 100/4 = 25ft
Area = 25^2 = 625 sq/ft
:
What is the largest circular kennel you can build?
This kennel will have a circumference of 100 ft, find the radius:
{{{2*pi*r}}} = 100
r = {{{100/(2pi)}}}
r = 15.9155 ft
find the area
A = {{{pi*15.9155^2}}}
A = 795.8 sq/ft
