The Spread of a Contaminant Is Increasing in a Circular

Question 292

Multiple Choice

The spread of a contaminant is increasing in a circular pattern on the surface of a lake.The radius of the contaminant can be modeled by , where r is the radius in meters and t is the time in hours since contamination.
Find a function that gives the area A of the circular lake in terms of the time since the spread began.
