How it's used
Mathematical terms like this are often used in academic or technical contexts, but they follow the same grammatical rules as everyday nouns. When discussing geometry in Cantonese, speakers often use the English loanword radius directly, especially in casual or professional settings where English terminology is standard.

Common mistake
Learners sometimes confuse 半徑 with 直徑, which means diameter. Remember that 半徑 is literally half the path from the center to the edge, while 直徑 spans the entire width through the center.
