Question

5) radius = 2.6 in
How do I find the circumference?

Answer 1

`\large\boxed{C=5.2\pi\ in\approx16.328\ in}`

Explanation:

The formula of a circumference of a circle:

`C=2\pi r`

r - radius

We have r = 2.6 in. Substitute:

`C=2\pi(2.6)=5.2\pi\ in`

`\pi\approx3.14\to C\approx(5.2)(3.14)=16.328\ in`
