Arc length = rθ ...(1)
where r is radius and θ is central angle in radians.
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.
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
