The relationship between the rates of change can be found by taking the derivative of area with respect to time.
... a(t) = π·r(t)²
... a'(t) = 2π·r(t)·r'(t)
At the time of interest, we have
... a'(t) = 2π·(6 ft)·(5 ft/min) = 60π ft²/min
The rate of change of area at that time is 60π ≈ 188.5 ft²/min.
