Chelsea boards a Ferris wheel at the 3 -o'clock position and rides for one full rotation. The Ferris wheel's radius is 11 meters long and its center is 15 meters above the ground. Imagine an angle with a vertex at the Ferris wheel's center subtending the path Chelsea has traveled since the Ferris wheel started rotating. Let θ represent this angle's measure in radians. Write a variable expression (in terms of
θ
) that represents Chelsea's height above the Ferris wheel's center (in meters).
