(A) Find the average rate of change of the area of a circle with respect to its radius r as r changes from (i) 5 to 6 →→ Average rate of change = (ii) 5 to 5.4 → Average rate of change = (iii) 5 to 5.1 → Average rate of change = (B) Find the instantaneous rate of change when r = 5. Instantaneous rate of change =
