Step-by-step explanation:
<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.
The answer for your question is thirteen
(3 + 2 - 5) and (4i - 3i + 6i)
= 0 + 7i
