Answer:

<h2>The radius r = 22.5 cm</h2>

Step-by-step explanation:

The formula of a circumference of a circle:

C=2\pi r

r - radius

We have the circumference

C=45\pi\ cm

Substitute:

2\pi r=45\pi               <em>divide both sides by π</em>

2r=45        <em>dvide both sides by 2</em>

r=22.5\ cm

Let's divide both sides by 10. (division prop. of equality)
1 second = 1.5 feet
