Answer 2

Answer:

12.57 cm

Step-by-step explanation:

The formula for circumference of a circle = 2πr

but here he had given the diameter in the question..

diameter(d) = 2 × radius(r)

r = d/2

r = 4/2

r= 2cm

so, the circumference of the circle = 2 × 3.14 × 2

                                                         = 4 × 3.14

                                                         => 12.57 cm
