Answer 2

SOLUTION ;
==========

$no. \: of \: revolutions \: in \: 1 \: min. \\ = 360$

$no. \: of \: revolutions \: in \: 1sec. \\ = \frac{360}{60} = 6$

$angle \: made \: by \: wheel \: in \\ 6 \: revolutions \: \\ 360 \times 6 = 2160$

$2160 \: degree \: = (2160 \times \frac{\pi}{180} )$

$= (12\pi)radian$
