<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.
Answer:
AB = 6.53
Step-by-step explanation:
cos theta = adjacent/ hypotenuse
cos 40 = 5/ AB
AB cos 40 = 5
AB = 5/ cos 40
AB = 6.527036447
Round to the nearest hundredth
AB = 6.53

Step-by-step explanation:
I knew the answer sir 112 but hmmm I'm only 7 g
Answer:
16 units
Step-by-step explanation:
You would take the area of the door (which would be 8 times 3) and subtract the area of the poster (which is 4 times 2).
Next, you would set up your equation: 24-8 which is 16.
Hope this helps! :)
