Nitroglycerin is often prescribed to enlarge blood vessels that have become too constricted. If the cross-sectional area of a blood vessel t hours after nitroglycerin is administered is A(t) = 0.01t2 square centimeters (for 1 ≤ t ≤ 5), find the instantaneous rate of change of the cross-sectional area 3 hours after the administration of nitroglycerin.
