Answer 2

The circumference of the circle is 12.56 km

Solution:

Given that,

Radius of circle = 2 km

We have to find the circumference of the circle

The formula for circumference of the circle is:

$C = 2 \pi r$

Where, "r" is the radius of circle

From given,

r = 2 km

Therefore,

$C = 2 \times 3.14 \times 2\\\\C = 6.28 \times 2\\\\C = 12.56\ km$

Thus circumference of the circle is 12.56 km
