Question 342570
<font face="Garamond" size="+2">


The circumference of a circle is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \pi{d}]


So the circumference of the original rug must be:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5\pi]


and since the rug with the border now has a diameter of *[tex \Large 5\ +\ y], the circumference of the rug and the border must be:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (5\ +\ y)\pi]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
