Question 1005163
By definition, {{{ pi }}} radians is a point
180 degrees from the 3 o'clock position
{{{ pi - 2.9 }}} is the angle in radians 
between the 9 o'clock position and 
{{{ 2.9 }}} radians
{{{ pi - 2.9 = .2416 }}} radians
{{{ sin( .246 )*2.9 = .23925}}}
----------------------
The car is .239 miles above the horizontal
This is the sin of the angle in  radians times
the radius in miles
