the circumference of a circle is C inches. The diameter of the circle is 17 inches. Which expression best represents the value of x?

1 answer

To find an expression that represents the value of \( x \) in terms of the given circumference \( C \) and diameter of the circle, we can use the relationship between the circumference (\( C \)) and the diameter (\( d \)) of a circle, which is given by the formula:

\[ C = \pi d \]

In this case, the diameter \( d \) is given as 17 inches, so we can substitute that value into the formula:

\[ C = \pi \times 17 \]

Thus, we have:

\[ C = 17\pi \]

If you're looking to express \( x \) in terms of \( C \), we can rearrange the formula:

\[ C = 17\pi \implies \pi = \frac{C}{17} \]

However, without further context about \( x \) and its relation to \( C \), it's not clear what expression is specifically required for \( x \). If you have additional information regarding how \( x \) is defined in relation to \( C \) or other parameters, please share, and I can provide a more tailored response. If \( x \) is simply referencing the circumference formula, you could say:

\[ x = 17\pi \quad \text{where } C = x \]

Or simply:

\[ x = C \quad \text{where } C = 17\pi \]

We can summarize that the expression for the circumference \( C \) reflects \( 17\pi \) when expressed as a function of the given diameter.
