Answer 7

your radius is 5 so put that in as r

Answer 8

2*pi*5

Answer 9

31.4

Answer 10

so now put that back into the first equation:
arc length/ circumference = arc measure/360

Answer 11

arc length/ 31.4 = arc measure/360

Answer 12

arc length/ circumference = 72/360

Answer 13

sorry i meant
arc length/ 31.4 = 72/360

Answer 14

can you solve for arc length yourself now?

Answer 15

well 31.4/360 is 0.2

Answer 16

you mean 72/360=0.2

Answer 17

a/31.4=0.2
a = 6.28

Answer 18

so the answer is 6.28
