If the radius of a circle is x/6, what's the diameter and circumference?
Diameter = 2*r
Circumference = 2*pi*r
...or...
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?

To determine the diameter and circumference of a circle with a radius of x/6, we need to substitute the given value of the radius into the formulas for each.
1. Diameter (d): The diameter of a circle is simply twice the radius.
d = 2 * r
In our case, the radius is x/6, so the diameter is:
d = 2 * (x/6) = (2x)/6 = x/3
Therefore, the diameter is x/3.
2. Circumference (C): The circumference of a circle can be calculated using either the formula C = 2πr or C = πd. Let's use the latter.
C = π * d
Substituting the value of the diameter we just found:
C = π * (x/3)
Therefore, the circumference is (πx)/3.
Now, let's talk about how to find the corresponding decimal values.
To get a decimal representation or approximation of x/6, we would need to know the specific value of x. If you have a particular value for x, you can substitute it into the expressions for diameter and circumference to get the decimal values.
For example, if x = 0.3, we can calculate:
Diameter: d = (0.3)/3 = 0.1
Circumference: C = (π * 0.3)/3 ≈ 0.314
Remember, without knowing the specific value of x, we can't provide a decimal answer.
