It drains at a constant rate using the first line find the rate per hour:

-3.5/2 = -1.75 per hour

Now to find the missing totals multiply the hours by the rate:

-1.75 x 9 = -15.75

-1.75 x 23 = -40.25

Now to find the change between the two times subtract:

-40.25 - -15.75 = -24.50

Answer:

$V = 1847.26\ ft^3$

Step-by-step explanation:

Step 1: Determine the volume

$V=\pi r^2h$

$V = \pi *(7\ ft)^2 * (12\ ft)$

$V = \pi *49\ ft^2 * 12\ ft$

$V = \pi * 588\ ft^3$

$V = 1847.26\ ft^3$

Answer: $V = 1847.26\ ft^3$
