3 meters is the same thing as 12/4 meters so divide 12/4 by 3/4 to get 4.
Answer:
(D)7 in.
Step-by-step explanation:
A regular hexagon can be divided into six equilateral triangles.
Therefore:

Applying Pythagoras Theorem

Recall that b=c/2
Therefore:

The value of b is 7 inches.

Hope this helped!
(By the way, I don't know why you're using hard formulas for trying to find the radius or diameter. The diameter is simply twice the radius, and the radius is simply half the diameter.)
