The mean sustained wind velocity, v, can be determined by the equation v= 6.3 square root 1013-p , where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?
For this case the equation is given by:  v = 6.3 * root (1013-p)  Clearing p we have:  root (1013-p) = v / 6.3  1013-p = (v / 6.3) ^ 2  p = 1013 - (v / 6.3) ^ 2  Substituting values:  p = 1013 - (64 / 6.3) ^ 2  p = 909.8002016 milibars  Answer:  The approximate air pressure at the center of a hurricane is:  p = 909.8002016 milibars
