32 ten thousands: 320,000
Answer: (x,y)---->(4x,4y)
Step-by-step explanation:
1. By definition, dilation is as a transformation in which the figure is enlarged or reduced.
2. For dilation you have:
- A scale factor, that determines how much the figure will be reduced or enlarged.
- The center of dilation, which is defined a a fixed point in the plane.
3. If the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply each coordinate of the original figure by 4, then. Then, the rule is:
(x,y)---->(4x,4y)
The rink has a dimension of 200 ft* 85 ft = 17000 
depth = 1.5 inch that becomes 
= 0.125 ft
So total volume of the water required = 17000* 0.125 = 2125 
Now 1 cubic foot of water= 7.480 gallons
Hence total gallons required are 2125 * 7.480 gallons = 15895 gallons.
