A high fountain of water is located at the
center of a circular pool as in the figure. A
student walks around the pool and estimates
its circumference to be 177 m. Next, the
student stands at the edge of the pool and uses
a protractor to gauge the angle of elevation of
the top of the fountain to be 45.6

.
How high is the fountain?

  1. 2 pi r = 177
    so
    r = 177/(2 pi)

    then
    tan 45.6 = h/r
    so
    h = r tan 45.6
