Answer:
V=πr^2(h/3)
Step-by-step explanation:
V=π6^2(8/3)
Plug them in... -4=x -5=y
-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)
-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)
Therefore the ordered pair IS NOT the solution.
Hope this helps :)
First calculate

.

We take positive value of sinθ because 0° < θ < 90°
Now we could calculate sin2θ, cos2θ and tan2θ:
