Answer 1

44

Explanation:

Answer 2

44

Explanation:

plug the given information into the formula for the circumference of a circle and solve for r

here's what that would look like:

`C=2\pi r`

1. plug the circumference in

`88\pi =2\pi r`

2. the pi would cancel out on both sides so you are left with:

`88=2r`

3. divide both sides by two

`44=r`
