He would make $1239.75
divide 4 in 2,204
multiply by 2.25
So she used

of the cord to make necklaces.

She splits the

length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.


She used

of the original chord to make each bracelet.
4(3-4x) . This is solved by factoring a 4 out of the equation. Distributing the 4 in the answer will provide the same equation as the one questioned.
Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
