Question

Find the radius of a circle with the given circumference 6√2π in. r =​

Answer 1

`\large\boxed{r=3\sqrt2\ in}`

Explanation:

The formula of a circumference of a circle:

`C=2\pi r`

r - radius

We have

`C=6\sqrt2\pi\ in`

Substitute:

`2\pi r=6\sqrt2\pi` divide both sides by 2π

`r=3\sqrt2\ in`
