Only answer if you're very good at math. No guessing please. A ferris wheel rotates around in 30 seconds. The maximum height above the ground is 55 feet, and the minimum height above the ground is 5 feet. Which function models the height as a function of t in seconds?

A: f(t) = 25sin π/15t + 30

B: f(t)= 30sin π/15t+25

C: f(t) = 25sin 2πt + 30

D: f(t)= 25 sin 60πt + 30​
