Answer 9

yes it's 565.2

Answer 10

its not wrong, but I think clarification is what you needed right @chicagochica05 ?

Answer 11

the answer was 180 not 360 :(

Answer 12

idk why it was 180 and not 360 and then it was 180 x 3.14

Answer 13

the equation you get in the book is 2 pi r = Circumference
r means radius. In this case, they give you the diameter
diameter = 2 times radius
so, C = pi * 2 r , OR C= pi * diameter
