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!

According to order of operations rules, exponentiation must be done first. Thus, we have

(3^2)*(3^2) = (9)(9) = 81.

Alternatively, note that there's only one base (3) here, even tho' it shows up more than once. So, 3^2*3^2 = 3^(2+2) = 3^4 = 81.
