Answer :

The answer would be 3392.92006588 yards. The formula for circumference of a circle is C=2πr so it would be 180 x 2 which is 360 then multiply that by pi which is 1130.97335529 and then you would multiply that by 3 to find the total which is  3392.92006588
use circumference formula which is c=2 times pi times radius

c=2 times pi times radius

radius=180
c=2 times 180 times pi
c=360 times pi
pi is aprox 3.14 so
c=360 times 3.14=1130.4 yards
that's one lap so multiply by 3
360π times 3=1080π
1130.4 times 3=3391.2
the answer is 1080π yards or 3391.2 yards
