Answer: The total distance Fiona covers in two laps of the race = 880 meters

Explanation:

Given : Fiona races BMX around a circular dirt course.

The radius of the course is 70 meters.

Then , Circumference of circular dirt course =
$2\pi (radius)$

=
$2*(22)/(7)*70=440\text{ meters}$
$[\text{Use }\pi=(22)/(7)]$

Now , the total distance Fiona covers in two laps of the race = 2 x (Circumference of circular dirt course)

= 2 x (440 meters)

= 880 meters

Hence, the total distance Fiona covers in two laps of the race = 880 meters
