Question 1049257
The wheel "unreels" 3 ft of it's circumference
Let {{{ C }}} = circumference
{{{ C = 2*pi*r }}}
{{{ C = 30*pi }}} in
--------------------
{{{ 3*12 = 36 }}} in wheel rolls forward
The angle in degrees that the wheel turns is:
{{{ 360*( 36 / ( 30*pi )) }}}
{{{ 432/pi = 137.51 }}}
 137.51 degrees
