Question 1058246
A flight simulator rotates to represent G-force on the body.  If it spins at {{{ 80 }}} revolutions-per-minute and has a radius of {{{ 20 }}} feet, how fast is it in feet per minute? 
A)  {{{ 1000 }}}
B)  {{{ 1800 }}} 
C)  {{{ 1800pi }}}
D)  {{{ 3200pi }}}
-----
Perimeter = 2*pi*r = 40pi ft.
------
rate = 80*40pi = 3200pi ft/minC
