OAB is a right triangle. Of this triangle, you know the hypothenuse (OA) and the longest leg (AB). You can find the radius, which is the shortest leg, by applying Pitagora.

r (OB) = √OA²-AB² = √9,8²-5² = √96,04-25 = √71,04 ≈ 8,4 (units?)

Answer:you would be charged $9.75 if you returned a book 65 days late

Step-by-step explanation:

The amount that the library charges when you return a book late is $0.15. If it is two days late, you are charged $0.30. It means that if it is a day late, the charge is 0.30/2 = $0.15. To determine how much you will be charged if you returned a book 65 days late, you will multiply the number of days by the amount charged for a day. It becomes

65 × 0.15 = $9.75
