Best ResponseYou've already chosen the best response.140 needs a pi, so 40*pi/180 = rads

Best ResponseYou've already chosen the best response.140*8 = 320 320 32 16  =  =  pi; i mighta inputed it wrong in me calculator; let me dbl chk 180 18 9

Best ResponseYou've already chosen the best response.0In general, when finding the arc length of a circle when given the radius and degree, you may use the following formula: \[\frac{\theta}{360°} = \frac{x}{2 \pi r}\] , x = arc length
