Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Tens place is 2
look to teh right
5> or = to 5 so round up:
412,830
The answer to the equation is 6
The answer should be X+6y=27
