Question

Can someone please help me!

Answer 1

Hello!

To find the circumference of a circle you do
`2 \pi r` where r is the radius of the circle

So we do 2
`\pi 72`

Then we substitute pi for 3.14

2 * 3.14 * 72 = 452.16 yds

Then we multiply this by 5 since he runs 5 laps

Which gives us the answer of 2260.8 yds

Hope this helps!
