Answer:
Step-by-step explanation:
Arc length=∅/360×2πr (can't find the symbol of theta, use ∅ instead LOL)
<h3>
Answer: 120 degrees</h3>
==============================================
Work Shown:
n = number of sides = 6
i = measure of interior angle
i = 180(n-2)/n
i = 180(6-2)/6
i = 180(4)/6
i = 720/6
i = 120
Each interior angle of this regular hexagon is 120 degrees.
-----------------
Alternative Approach:
E = exterior angle
E = 360/n
E = 360/6
E = 60
Each exterior angle of this regular hexagon is 60 degrees
i+E = 180
i = 180-E
i = 180-60
i = 120
We get the same answer.

Answer:
Height= 18cm
Step-by-step explanation:
Curved surface area = 2πrh
108π = 2 * π * 3 * h
108π = 6πh
h= 108π ÷ 6π
h= 18cm
