Question

What is the circumference of a circle with radius 5 feet?

Answer 1

Formula:\[C = 2 \pi r\]

Answer 2

Now, we substitute what we know:\[C = 2 * 3.14 * 5\]

Answer 3

The circumference formula is \[2\Pi r\]Your radius is 5 feet. So plug in 5 for r and solve \[2\times \Pi \times 5\]

Answer 4

\[C = 2 \pi r = 31.42\]

Answer 5

And \(\pi\) is equal to 3.14, by the way.

Answer 6
