<h3>
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.

Step-by-step explanation:
if it is a sample and there are 5 diffrant things that is supposed to be in there, the 5 would be just rediculus, if it is 10, that would make more sense. 40, that would be more like the regular versian of it
