Answer:The answer is 18.84


Step-by-step explanation:To figure out the circumference of a circle you need to divide the radius by 2. After that you would do
2\pi * ( your number ) * 2

Greetings!

Answer:

18.84 (or 19 to 2.s.f)

Explanation:

The formula for the circumference of a circle is π * diameter. To find the diameter you multiply the radius by 2:

3 * 2 = 6

Then simply plug the value into the formula:

π * 6 = 6π ≈ 18.84 ≈ 19 to 2.s.f


Hope this helps!
