I need help whit math​

Suppose investors can earn a return of 2% per 6 months on a treasury note with 6 months remaining until maturity. the face value of the t-bill is $10,000. what price would you expect a 6-month maturity treasury bill to sell for? (round your answer to 2 decimal places. omit the "$" sign in your response.)

We just started the introduction into circles and i have no idea how to do this.

Asap! i'm not good math and i'm lost.
