Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 12? Use 3.14 for π and express your answer to the hundredths place. Thank you.

Answer 1

To find the approximate circumference of a circle using the formula \( C = 2\pi r \), where \( r \) is the radius, you can substitute the given radius and the value of π.

Given:

• Radius (\( r \)) = 12
• π ≈ 3.14

Now, substituting the values into the formula:

\[ C = 2 \times 3.14 \times 12 \]

First, calculate \( 2 \times 3.14 \):

\[ 2 \times 3.14 = 6.28 \]

Next, multiply this result by the radius:

\[ C = 6.28 \times 12 = 75.36 \]

So, the approximate circumference of the circle is \( 75.36 \).

Thus, the answer expressed to the hundredths place is 75.36.
