You have a wire that is 38 cm long. you wish to cut it into two pieces. one piece will be bent into the shape of a square. the other piece will be bent into the shape of a circle. let a represent the total area of the square and the circle. what is the circumference of the circle when a is a minimum?

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2r=x
r=
Area=r^2
so..
A=()^2
=()
=

(38-x) is perimeter
then 

()^2
+ ()^2
then you graph it and it equals
16.716 cm the circumference of the circle

After the experience with great britain having a monarchy, the united states realized that everyone needed to have a voice in the government. the fact that americans had no voice was the main reason for the war. thus, they created a democracy, where the people voted for their representatives and the government ruled with the consent of the people.
