Understand that the radius is the distance from the center of an object to its outer edge or surface.
Consider the typical sizes of each object: a proton is subatomic and extremely small, on the order of 10^{-15} meters.
A human hair has a radius roughly around 10^{-5} meters, which is much larger than a proton but still very small.
A basketball has a radius of about 0.1 meters, significantly larger than a human hair.
The Earth has a radius of approximately 6.4 \(\times\) 10^{6} meters, which is vastly larger than all the other objects listed.
