meters  by  5   meters  and the 108 cubic   meters  of  added   volume, you can figure  out what    the

added   depth   is:

That’s  on  top of  the pre-existing    12.5    meters. The new water   level   is  12.5    +   7.2 =   19.7    meters.

The equation for a circle centered at (3,2) and with radius r = 5 is

(x  −   3)^2    +   (y  −   2)^2    =   25

To  find    where   the graph   of  this    equation    intersects  the x-axis, set y   =   0   and solve   for x:

31 . E

Between 0   and π,  tangent is  defined for anything    but  .  Sine    is  defined for all values  of  x,

but since   the sine    is  in  the denominator here,   the expression   will   be  undefined   when

sin x   =    0 ,    which   is  when    x   =   0 or    π.  So  the expression   is defined when

32 . C

Use the given   volume  =   50  to  get h   in  terms   of  x:
