Suppose five circles, each 4 inches in diameter, are cut from a rectangular strip of paper 12 inches
long. If the least amount of paper is to be wasted, what is the width of the paper strip?
a=sqrt(3)  Pick.
A) 5
B) 4 +2a
C) 8
D) 4(1+ a)
E) not enough information
Also if we dont go by 30:60:90 rule, we can arrive at the length of by pythagoras theorem.   (AC)^2 + (BC)^2 = AB^2   (AC)^2 + 2^2 = 4^2   AC = 2 root b.   so the width of paper = 2 + 2 + 2 root 3 --&gt; 4 + 2 root 3.   which is 4 +2a.
