Answer:

b. 75.40

Step-by-step explanation:

The circumference of a circle is the perimeter of the circle. To find the perimeter we would use the formula ⇒ 2 × π × r ⇔ or π × d ← where r is the radius and d is the diameter .

So lets substitute in the values

2 × π × r

Radius = 12

2 × π × 12 = 24 π = 75.3982236862

So the answer is b. 75.40
