circumference = angle * r, any arc length is angle * r
amistre64
  • amistre64
turn the angle to rads tho

Yeah, amistre has it. I was thinking about something else.
amistre64
  • amistre64
40 needs a pi, so 40*pi/180 = rads
amistre64
  • amistre64
and go ahead an multiply in the radius as well

i dnt get it answer choices are 8/9 , 16/9 or 64/9

\[Arc_{length}=\frac{degree*pi*radius}{180}\]

I get 8/9 pi when I do it

40*8 = 320 320 32 16 --- = -- = -- pi; i mighta inputed it wrong in me calculator; let me dbl chk 180 18 9

1 7/9 = 16/9 got it right that time lol

In 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
