Suppose Asha is on a Ferris wheel of diameter 60 meters. She boarded the Ferris wheel at ground level, at the 6:00 position, and the wheel has turned counter-clockwise $\frac{11\pi}{8}$ radians. How high off the ground is she? Give both an exact solution and a decimal approximation. [Hint: Try sketching a picture of the situation first.]

The exact height (given in meters) is...

A. $30-30\sqrt{\frac{1+\sqrt{2}/2}{2}}$
B. $30-\sqrt{\frac{1-\sqrt{2}/2}{2}}$
C. $-30\sqrt{\frac{1+\sqrt{2}/2}{2}}$
D. $30\sqrt{\frac{1-\sqrt{2}/2}{2}}$
E. $30+\sqrt{\frac{1+\sqrt{2}/2}{2}}$
F. $30+30\sqrt{\frac{1+\sqrt{2}/2}{2}}$
G. $30-30\sqrt{\frac{1-\sqrt{2}/2}{2}}$
H. $30-\sqrt{\frac{1+\sqrt{2}/2}{2}}$
I. $30+30\sqrt{\frac{1-\sqrt{2}/2}{2}}$
J. $30+\sqrt{\frac{1-\sqrt{2}/2}{2}}$
K. None of the above
The decimal approximation of Asha's height is meters.
