The circumference of the circle formula is 2πr or πd.
We will use πd since we know the diameter.
C = πd
C = (3.14)(16)
C = 50.24
Hope this helps :)
.394= 197/500
you can't make it a mixed number since there isn't a whole number as with an improper fraction.
The length would be 40 feet... 100*2=200/5=40

The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
