Question

If a circle has a radius of 38 inches
, what is its approximate circumference to the nearest hundredths? Use 3.14
for π
.(1 point)

Answer 1

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

\[
C = 2\pi r
\]

where \( r \) is the radius of the circle.

Given that the radius \( r = 38 \) inches and using \( \pi \approx 3.14 \):

\[
C = 2 \times 3.14 \times 38
\]

Now, calculate it step by step:

\[
C = 2 \times 3.14 = 6.28
\]
\[
C = 6.28 \times 38 \approx 238.64
\]

Thus, the circumference of the circle is approximately **238.64 inches** to the nearest hundredths.
