Answer:
##
Step-by-step explanation:
Volume of Cylinder =

Based on what we're told:
r (radius) =

h (height) =

So:
Volume of cylinder =

=
14x-14>7x+7
14x - 7x > 7 + 14
7x > 21
x > 21/7
x > 3
This is an impossible equation. If sqrt(x) = sqrt(x), and sqrt(x) + 2 = sqrt(x) + 12, then that would mean that 2=12, which is incorrect.
