noun, suffix
This is the noun version of the kanji circumference, so it means circumference too.
まわり
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: You really want to measure the circumference of something but there doesn't seem to be anything round around. That's when you remember, "Mah Walnuts! (まわ)." The walnuts in your pocket have an easy edge to measure.

大好きな事があるなら、周りが何と言おうと、それをやりつづけるべきだよ。
If there's something you love, you should stick with it regardless of what the other people say.
いつも周りの目が気になるんです。
I'm always worried about what other people are thinking about me.
