1 answer

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 \( r \) is 38 inches and using \( \pi \approx 3.14 \):

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

Calculating this step-by-step:

  1. First, calculate \( 2 \times 3.14 \): \[ 2 \times 3.14 = 6.28 \]

  2. Next, multiply this result by the radius (38): \[ 6.28 \times 38 = 238.64 \]

Thus, the approximate circumference of the circle is:

\[ \boxed{238.64} \text{ inches} \]
