what is the circumference of a circle with a radius of 3 feet? estimate the circumfrence to the hunndredths place using 3.14 for pi

Answer 1

To calculate 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 3 feet and using \( \pi \approx 3.14\):

\[ C = 2 \times 3.14 \times 3 \]

Now, calculate it step-by-step:

1. First calculate \(2 \times 3.14 = 6.28\).
2. Now multiply that by the radius (3): \[ C = 6.28 \times 3 = 18.84 \]

Therefore, the circumference of the circle is approximately 18.84 feet when rounded to the hundredths place.
