Question

A circle with a radius of 12 would have a circumference of ____

Answer 1

`\huge\boxed{75.36}`

Explanation:

In order to find the circumference of a circle, we can use the formula for it, which is
`2 \pi r`.

This formula states that r, the radius, multiplied by pi (3.14..) doubled will be the circumference.

Pi rounds to 3.14 usually.

So our new formula is:

`2 \cdot 3.14 \cdot 12`

We can now multiply.

`3.14 \cdot 2 = 6.28\\\\6.28 \cdot 12 = 75.36`

Hope this helped!
