Answer:
You can look down
Step-by-step explanation:
Okay so you can put this has a mixed faction.
so it is 46/3. and then you can simplify it and you get the same answer. 14 2/3 but you still cant simplify it because all numbers are un-even. like you cant simplify.

Answer:    18pi</h3>
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
