Question

Find the circumference

Answer 1

25.12 m (or 25.13 m)

Explanation:

Recall the formula for the circumference of a circle:

`2\pi r`

where r is the radius.

We are given that the radius is 4 m, so let's plug that into our formula:

`2\pi r=\\2\pi *4=\\8\pi`

`\pi` is approximately 3.14, so let's multiply 8 m by 3.14. We get:

25.12

So, the circumference is about 25.12 m.

(if you multiply by pi itself using a calculator, the answer is about 25.13 m)
