What is the arc length if the central angle is 225 degrees and the radius of a circle is 3 cm?
pls help. i don"t get it

Arc length = rθ ...(1)

To convert 225° to radians, multiply by (π/180) to get 225π/180=5π/4

Use formula (1) to calculate arc length, which should be in the same units as the radius.

2*225*pie/360*3
