12 ft.

Shape: Circle
Circumference Formula: C = 2πr
What is the circumference of a circle with a radius of 12 feet?
Use 3.14 for pi (π).
C = [?] ft.
Do not round the answer.
75.36? WRONG!

1 answer

To find the circumference of a circle using the formula \( C = 2\pi r \), where \( r \) is the radius, we can plug in the value for the radius.

Given:

  • Radius \( r = 12 \) feet
  • Use \( \pi \approx 3.14 \)

Now, calculate the circumference:

\[ C = 2\pi r \] \[ C = 2 \times 3.14 \times 12 \] \[ C = 6.28 \times 12 \] \[ C = 75.36 \text{ ft} \]

So the calculation is correct, and the circumference of a circle with a radius of 12 feet is indeed \( C = 75.36 \) ft. If you received "WRONG!" feedback, it may have been due to a misunderstanding of the question or the expected format of the answer.
