Answer:

12 is the best estimate

Answer:

option A.

Step-by-step explanation:

We have to find the circumference of the given circle with radius 2 units.

Since formula to calculate circumference of a circle is = 2πr

Where r = radius of the circle.

Circumference = 2 × (3.14) × (2)

                        =  4 × 3.14

                        = 12.56

So approximate value will be option A.
