Hi, 21:51 why did you count each of OC and OD as r and not 2r?

Hi thanks for watching. You are finding the perimeter which is just the distance around the outside of the logo and of the 2r radius on the larger sector only one r is on the perimeter as the other r is inside the shape. Hope that makes sense :)

Oh alright, thank you :)@@gcsealevelmathstutor5665
