Question

If a radius is 14 inch, then what is the circumference of the circle rounded to the nearest tenths place?(1 point)
The circumference is
inches.

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.

Given that the radius \( r \) is 14 inches, you can substitute this value into the formula:

\[
C = 2\pi (14)
\]
\[
C = 28\pi
\]

Now, using the approximate value of \( \pi \) (3.14), we can calculate:

\[
C \approx 28 \times 3.14 = 87.92
\]

Rounding 87.92 to the nearest tenths place gives:

\[
\text{Circumference} \approx 87.9 \text{ inches}
\]

Thus, the circumference of the circle is approximately **87.9 inches**.
