Circumference of the circle \(C =2 *\pi * radius = 6\pi\)

Diameter of circle \(C = 2 * radius = 6\)

QTY A = \(\frac{{6\pi}}{6}= \pi = \frac{22}{7}\)= greater than 3

Hence QTY A > QTY B

Nice question!
The best part is that the circle's radius is irrelevant here, since circumference/diameter = π for every circle in the universe.
So, we get:
Quantity A: π
Quantity B: 3

Answer: A

Cheers,
Brent
