Hurricane Sandy, which hit the New Jersey coast on Oct.
29, 2012, was extremely broad, with wind velocities of
40 mi/h at 400 miles from its center. Its maximum velocity
was 90 mi/h. Using the model of Fig. , at 20°C with a
pressure of 100 kPa far from the center, estimate (a) the radius
R of maximum velocity, in mi; and (b) the pressure at r = R.
