The static friction case is similar for when the two surfaces are stationary relative to each other. ... In this lab, students will measurecoefficients of friction and show that the frictional force doesn't depend on surface area in contact. Also, thecoefficient of friction doesn't depend on the mass of the object

As the radius changes, area changes and so the surface area of contact changes......
