Answer: The total distance Fiona covers in two laps of the race = 880 meters
Step-by-step explanation:
Given : Fiona races BMX around a circular dirt course.
The radius of the course is 70 meters.
Then , Circumference of circular dirt course = [tex]2\pi (radius)[/tex]
= [tex]2\times\dfrac{22}{7}\times70=440\text{ meters}[/tex] [tex][\text{Use }\pi=\dfrac{22}{7}][/tex]
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
