Answer:
I have no idea sorry :c
Step-by-step explanation:
C = 2 x pi x r
divide each side by 2 x pie to get r by itself.
45/(2(3.14)) = r
r = 7.17
Hope this helps! :)
There is an explanation in the photo below, as well as some things to remember!
126 1/4 - 78 2/3 =
505/4 - 236/3 =
1515/12 - 944/12 =
571/12 =
47 7/12 <==
If you mean 720/10^3, you do 10*10*10. This equals 1000. Now, do 720/1000. This is 0.72, or 72/100, which is your answer.
