The volume of a cylinder is given by

Let
and 
The new volume becomes

So, the new volume is 8 times the original volume. In fact, volume scales linearly with the height and quadratically with the radius.
Answer:
90t-21t=69t
Step-by-step explanation:
4:00pm to 6:00 am is 14 hours. 14 x 1.5 is in fact 21 which means the temperature dropped 21 degrees in those 14 hours.

Subtract 4 from both sides.

Subtract 4 from 36 to get 32.

Divide both sides by −8. Since −8 is <0, the inequality direction is changed.

Divide 32 by −8 to get −4.
