If the radius of a circle is x/6, what's the diameter and circumference?
Diameter = 2*r
Circumference = 2*pi*r
Circumference = pi*d
Note: I'm using * to mean multiply.
Can you now determine what you need to know with this information?
Not really. I just need to know how you can take the fraction x/6 and multiply it by two. How do you get an answer of 0.3?
