A girl sitting on a merry-go-round moves counterclockwise through an arc length of 3.15 m.

If the girl’s angular displacement is 1.82 rad, how far is she from the center of the merry-go-round?

Answer in units of m

Verified Answer :

Well, you get the movement as the arc in radians times the radius, which we need to find. Doing \(\frac{3.15}{1.82}=1.73\), which is about \(\sqrt{3}\) meters.
