12 ft.

Question

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.

Answer 1

To find the circumference of a circle, you can use the circumference formula:

\[ C = 2\pi r \]

Given that the radius \( r \) is 12 feet, we can substitute \( r \) into the formula:

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

Now, let's calculate it:

\[ C = 2 \times 3.14 \times 12 = 6.28 \times 12 \]

Now multiply \( 6.28 \) by \( 12 \):

\[ C = 75.36 \]

Therefore, the circumference of the circle is

\[ C = 75.36 \text{ ft} \]
