The solution to the questions are:
- The value of 
. As a consequence, the radius of the circle is equal to the length of the segment AB. 
- AB = BC =CA = R. As a consequence, the radius of the circle is equal to the length of the segment AB.   
 
- The perimeter of the hexagon is equal to r times 6. As a result, the number 6r represents the hexagon's perimeter.
 
- P=6.28r. As a result, the diameter of the circle is a fraction of a unit bigger than.
 
- P=6.28r. As a result, the diameter of the circle is a fraction of a unit bigger than.
 
<h3>What is the length of segment AB?</h3>
1) Generally, the equation for  m∠ACB is  mathematically given as
CA= CB
CA = radius of the circle
Therefore,
∠CAB = 

the sum of all the angles of a triangle
the sum of all the angles of a triangle is 180°




 The value of 
.
2. What is the length of segment AB?
In the same manner, as in ACB, all of the angles are the same. As a result, we may say that the triangle has equal sides.
In a triangle with equilateral sides, each of the triangle's three sides has the same length.
AB = BC =CA = R
As a consequence, the radius of the circle is equal to the length of the segment AB.
<h3>3. What is the perimeter of the 
hexagon?</h3>
The formula for calculating the hexagon's perimeter is 6a, where an is the number of sides in the hexagon.
The circumference of the hexagon is equal to 6 times a.
The circumference of the hexagon is equal to six times each side (AB)
The perimeter of the hexagon is equal to r times 6.
As a result, the number 6r represents the hexagon's perimeter.
4. The perimeter of the hexagon is  6r the circumference of the circle.
- the perimeter of the hexagon = 6r
 - the perimeter of the circle = 
  

P=2*3.14*r
P=6.28r
As a consequence of this, the hexagon's perimeter is less than the diameter of the circle.      
5. The circumference of the circle is 6.28r.
the perimeter of the circle = 

P=2*3.14*r
P=6.28r
As a result, the diameter of the circle is a fraction of a unit bigger than.
