83. AMUSEMENT PARK RIDE A ride at an amusement park
consists of two circular rings of swings. At full speed the
swings in the inner ring travel on a circular path with a
radius of 32 feet and the swings in the outer ring travel on
a circular path with a radius of 38 feet. Each swing makes
one complete revolution every 3.75 seconds. How much
greater, in miles per hour, is the linear speed of the swings
in the outer ring than the linear speed of the swings in the
inner ring? Round to the nearest tenth of a mile per hour.
84. HORSE RACING The semicircular turns of a horse race track
each have a radius of 200 feet. During the first turn of a race,
the lead horse is running near the inside rail on a path with
a 202.0-foot radius, at a constant rate of 24.4 feet per second.
A second horse is rounding the same turn on a path with
a 206.5-foot radius. At what constant rate does the second
horse need to run to keep pace with the lead horse during
this turn? Round to the nearest tenth of a foot per second.
85. ASTRONOMY At a time when Earth was 93,000,000 miles
from the sun, you observed through a tinted glass that the
diameter of the sun occupied an arc of 31'. Determine, to
the nearest ten thousand miles the diameter of the sun.
