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

1 answer

The formula for the circumference \( C \) of a circle is given by:

\[ C = 2\pi r \]

where \( r \) is the radius. Given that the radius is 14 inches, we can plug in that value:

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

Calculating this gives:

\[ C = 28\pi \]

Using the approximation \( \pi \approx 3.14 \):

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

Now, rounding to the nearest tenths place:

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

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