Distance a rotating turnable moves

[preluderacer]

Homework Statement

The radius of a rotating turntable is 2.2 m. If it turns through an angle of 1.1 radians, through what distance does a point on the edge move?

The Attempt at a Solution

I can't find an equation that will give me the distance. Is this like 2 parts or am I just blind to see this equation?

do you know the equation for the circumference of a circle?

 

[preluderacer]

is it just radians x radius?

 

[preluderacer]

Ok I got the circumference do I just multiply it by the radians?

 

[preluderacer]

im still lost on this any inputs?

What would you do if it was degrees instead of radians?

(degrees turned)/(total degrees possible 360) x circumference

Now replace the degree portion with a Radian equivalent.
