Answer:
4 cm

Explanation:
Radius = 4

Using the formula: (This is just for radius):
(8π-12√³)

Use the radius to work out circumference:
C==2 π r==2··π··4=≈25.13 cm

Divide the circumference by 6 because the AB curve is 1/6 of the whole circumference:

25.13 divided by 6 = 4.188333333333333

(Corrected to 1 sig fig) 4 cm


Side note:
It is not 4 (with the pi sign at the end),
this is because the numbers do not go on infinitely.
