Question

A circle has a diameter of 7 centimeters and a circumference of approximately 21.98 what expression best represents the value of pi

Answer 1

To find an expression that represents the value of \(\pi\), 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 \(d\) of the circle is 7 centimeters, and the circumference \(C\) is approximately 21.98 centimeters. We can rearrange the formula to solve for \(\pi\):

\[
\pi = \frac{C}{d}
\]

Substituting the given values of \(C\) and \(d\):

\[
\pi \approx \frac{21.98}{7}
\]

Now, we can compute this expression:

\[
\pi \approx 3.14
\]

So, the expression that best represents the value of \(\pi\) in this context is:

\[
\frac{21.98}{7}
\]
