**bobpursley**, Sunday, April 11, 2010 at 5:01pmdraw a triangle from the diameter horizontal, up from the horizontal 3m to intersect the circle, then the hyp is the radius back to the center.

h=3m so 3/5 = sinTheta theta= 36.8deg

So the person is below nine meters then the bottom 180deg, and the top each side 36.8 deg, or a total of 253.7 deg, or

253.7/360 percent of the time.

time above= 5min*253.7/360
