Consider a triangle with vertices $( 0,0 ) , ( 1,2 )$ and $( - 4,2 )$. Let $A$ be the area of the triangle and $B$ be the area of the circumcircle of the triangle. Then $\frac { B } { A }$ equals\\
(A) $\frac { \pi } { 2 }$.\\
(B) $\frac { 5 \pi } { 4 }$.\\
(C) $\frac { 3 } { \sqrt { 2 } } \pi$.\\
(D) $2 \pi$.
