.
A circular athletic field has a radius of 70cm.a running track 6m wide surrounds it.what is the area of the running track?
~~~~~~~~~~~~~~~~~~~~


<pre>

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.
