The radius of a floppy disk refers to the distance from the center of the disk to the edge.
Micro floppy disks are a type of floppy disk that were used in the 1980s and 1990s for data storage. There were two common sizes of micro floppy disks: 3.5 inches and 5.25 inches.
The radius of a standard 3.5-inch micro floppy disk is approximately 34.94 millimeters or 1.38 inches. However, it's worth noting that the term 'micro floppy' is not commonly used anymore, as these disks have been largely replaced by other storage media such as USB flash drives and cloud storage.
