For some reason it's forcing me to crop the question before it's all in the photo. There's another part to this question that says, "Find the average temperature during the period from 9 am to 9pm." Please answer that one as well. Idk why I can't get it to post with this. Thank you so much in advance!!

In a certain city the temperature (in degrees Fahrenheit) t hours after 9am was approximated by the function art T(t) = 40 + 12 sin () 12 Determine the temperature at 9 am. Determine the temperature at 3 pm
