Explanation
Quantity A: The circumference of circle A minus circumference of circle B
Quantity B: 72
The radius of circle A is 12 greater than the radius of circle B
Let x = radius of circle B
So, x + 12 = radius of circle A
Circumference of circle = 2π(radius)
So, circumference of circle A = 2π(x + 12) = 2πx + (2π)(12) = 2πx + 24π
Circumference of circle B = 2πx
We get:
Quantity A: (2πx + 24π ) - 2πx
Quantity B: 72
Simplify to get:
Quantity A: 24π
Quantity B: 72
Divide both quantities by 24 to get:
Quantity A: π
Quantity B: 3
Since π ≈ 3.14, we can see that quantity A is greater

The radius of circle A is 12 greater than the radius of circle B
Quantity A
The circumference of circle A minus circumference of circle B
We know that the circumference of a circle with radius r = 2πr
So, circumference of A - circumference of B = 2π(Radius of circle A) - 2π(Radius of circle B)
= 2π* (Radius of circle A - Radius of circle B) = 2π* 12 ( As Radius of circle A is 12 greater than Radius of circle B )
= 2*3.14 *12 = 75.36 (π=3.14)
Clearly, Quantity A (75.36) > Quantity B (72)
So, answer will be A
Hope it helps!
