Answer:
A. 
Step-by-step explanation:
Given:
Volume of the cylindrical container before dilation, 
Scale factor of the dilation, 
Therefore, the volume of the dilated cylinder is given as:

Plug in 1 gal for
and
for SF. Solve for
. This gives,

Therefore, the volume of the dilated cylinder is
gallons.
The answer is 13.
Because this is a kite, the diagonals intersect perpendicularly or with a 90° angle.
In the triangle DIC, which is a right triangle, the legs are 5 and 12. To find the hypotenuse, we use Pythogarean theorem:

Plug in the givens:

Take the squares:

Take the square root of both sides:

We find the line segment DC. In the question it says "BD = DC". So BD is equal to 13.
