Hello!
So the arc formula is as follows: s=r*theta where theta is in radian form ONLY!
We can get degvto radians by multiplying the degree measure by (pi/180) so stunning that into our equation we get;
s=(65)(pi/180)(6.48in)
s=7.35inches or 7.4in to the nearest tenth, is the length of arc RQ
Hope this helps and any questions feel free to ask. Thank you!
