When oil was spilled out in the middle of a lake, it spread out on the surface of the water in a circular pattern. The radius of the circular pattern increased at a rate of 3.5 feet per minute. (r(t) = 3.5t ft/min A. How fast was the area of the circular pattern increasing per minute? Construct the composite function to show how the area was increasing each minute. (A(r) = mr2 f2 /min ). 3. Find the radius of the circular pattern of oil 150 seconds after the oil starts to spread. C. Find the area of the circular pattern of oil 4 minutes after the oil starts to spread.
