Question

If a circular track has a radius of .05 of a mile, what is the distance around the track? 0.03 mile 0.14 mile 0.31 mile 0.34 mile

Answer 1

0.31 miles.

Explanation:

Distance around the track = 2 π r

= 2 * π * 0.05

= 0.31 miles.

Answer 2

About 0.31 miles

Explanation:

The circumference of a circle is
`2\pi r`. Plugging in the given radius, you get:

`2 \cdot \pi \cdot 0.05=0.1\pi \approx 0.31`

Hope this helps!
