Please Help! Trig Question!

3*(25/360).-Distance traveled=(4.3*pi)*(25/180) = 1.876 or cm or 1.88 cm along the arc of a circle with radius 4.3 cm.......
A pendulum of length 4.3 centimeters swings through an arc of 25 degrees how far does the tip of the pendulum travel to the nearest tenth of a centimeter?

-
You can interpret the length of the pendulum as the radius of a circle.

The arc also tells you what portion of the circumference the pendulum travels.

That should give you a couple things that are pretty straightforward to calculate. I get 2*pi*4.3*(25/360).
