Yeah i found that already but the problem doesn't ask you to completely ask you to solve it the options are
A.0.7pi
B.1.4pi
C.1.96pi
D.2.8pi
and i chose D

Answer 6

you are correct.
8.8 divided by PI/3.14 = 2.8, and that brings you to 2.8pi

Answer 7

So here you would do 2r and just add the pi to the end
