Volume of sphere: 
, put $r=5 in$
Volume of cylinder:$ \pi r^2 h$, put $r=8 in, \: h=11 in$
terms is x first then terms in y and constant after the equals
Its C
C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.
Hope that helps.
Angles XQL and MQR are congruent because they are vertical angles. So
209 - 13 <em>b</em> = 146 - 4 <em>b</em>
Solve for <em>b</em> :
209 - 13 <em>b</em> = 146 - 4 <em>b</em>
209 - 146 = 13 <em>b</em> - 4<em> b</em>
63 = 9 <em>b</em>
<em>b</em> = 63/9 = 7
Then the measure of angle XQL is
(209 - 13*7)º = 118º
