Question

If a radius is 14
1
4
inch, then what is the circumference of the circle rounded to the nearest tenths place?

Answer 1

To find the circumference of a circle, you can use the formula:

\[ C = 2\pi r \]

where \( C \) is the circumference and \( r \) is the radius. In your case, the radius \( r \) is \( 14.4 \) inches.

Now, we can calculate the circumference:

\[
C = 2 \times \pi \times 14.4
\]

Using \( \pi \approx 3.14 \):

\[
C \approx 2 \times 3.14 \times 14.4
\]
\[
C \approx 6.28 \times 14.4
\]
\[
C \approx 90.192
\]

Now, rounding to the nearest tenths place, the circumference is:

\[
C \approx 90.2 \, \text{inches}
\]

Thus, the circumference of the circle is approximately **90.2 inches.**
