Answer:

Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
, where s is time in seconds.
When s=5
Radius 
Area of a circle 
Therefore, the area of the oil spill when s=5 seconds

The area of the spill when s=5 seconds is 45pi square inches.
Let’s call the number “n.” 0,32n=64 (32% is 32 per cent-, or per hundred), and n=64*100/32=100*2=200. Therefore, the answer’s D.
