What is the circumference of this circle?

Step-by-step explanation: To find the circumference of

the circle shown here, start with the formula c = 2πr.

Since the radius is 2 km, we can plug is 2 km for r in the formula.

So we have (2)(π)(2 km) which is equal to 4π km.

Now, remember that π is approximately equal to 22/7 or 3/14.

So we can estimate the value of the

circumference by plugging in 2.14 for π.

So we have (4)(3.14) which is equal to 12.56.

So the circumference is approximately equal to 12.56km.

your answer would be 7
