Answer 4

convert iy @kausarsalley

Answer 5

could you go into detail how you got the answer though? I am so lost

Answer 6

30 degrees= pi/6 radians

Answer 7

now
2pi=pi/6*r

Answer 8

divide pi from both the sides now calculate it and u get r=12

Answer 9

how do you get 6 radians?

Answer 10

I thought it was pi times 2π on that one side, and I am clueless how it turns into 6

Answer 11

thank you though!
