The formula for finding the sum of the measure of the interior angles is (n - 2) * 180
(5-2)×180= 3×180=540
To get each interior angles
540/5 = 108
180 -108 = 72
To get x
72+72+x= 180 (sum if angles in a triangle)
144+x= 180
x = 180 -144 = 36
2. x is part of the interior angles = 108

Hope this helps
Step-by-step explanation:
first you need to find the circumference...
2pi R (r=radius=11)
2 x 3.14 x 11 = 69.08 (i'm using 3.14 as pi so yea...)
3 rotations...
69.08 x 3= 207.24 inches
