Liquid leaked from a damaged tank at a rate of r(t) liters per hour. The rate decreased as time passed and values of rate at three-hour time intervals are shown in the table t (hr) r (L/h) 8.2 7.8 7.5 7.2 6.9 12 15 6.6 Find lower and upper estimates for the total amount of liquid that leaked out lower estimate = 1 /0 8 upper estimate = L. / r2. 8 liters liters 10 (6,7.5) (0, 8.2) (12, 6.9) (3, 7.8) (9, 7.2) (15, 6.6) 10 Left Riemann Sum Right Riemann Sum 0 0 2 7.5 7.2 6.9 6.6 112.8 108 12 15
