In a trend that scientists attribute, at least in part, to global warming, a certain floating cap of sea ice has been shrinking since 1980.
The ice cap always shrinks in the summer and grows in winter. Average minimum size of the ice cap, in square miles, can be
approximated by A= piR^2. In 2013, the radius of the ice cap was approximately 792 mi and was shrinking at a rate of approximately
4.1 mi/yr. How fast was the area changing at that time?
The area was changing at a rate of in 2013.
(Round to the nearest integer as needed.)
