The measurements must be equal to each other.
Not always. The direction is only necessary if you're discussinga distance vector, but you're usually not.
I don't know, that's why i asked !!:DD I'm guessing its some kind of two measurements!xD
Yes they must be in the same units of measurements.
The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
Patient status
Individuals must give informed consent for any physiological measurements taken, and their privacy and confidentiality must be maintained. Researchers must follow ethical guidelines and obtain any necessary approvals from regulatory bodies before conducting any measurements. Additionally, researchers must ensure that data collection and analysis procedures are accurate and reliable.
If you don't give a unit how will people know what you are talking about. For example if I say my car is 45 what does that mean??? 45 years old, 45 horse power 45 feet long, 45 metres long, 45 tons get the idea ?

Units.
Such measurements vary from person to person. This type of question should be directed towards your doctor who will be able to give you a more accurate answer based on your current stats, measurements, genetics and family history.
All ratio measurements must be in the same units before simplifying
If you are always vigilant, you will be safe. One must remain vigilant.
