~~~~~~~~~~~~~~~~~~~~ 


The area of the running truck is the difference of the areas of the larger and smaller circles.


    I do not believe that the radius of the athletic field is 70 cm.


    I think it is 70 meters.


    Therefore, I do not perform calculation for this problem.


Double check with your source this data 70 cm for the radius of a circular athletic field.

It's a running track for bugs.
Not for that recently mentioned car with wheels of diameter 10 meters.
