Please answer these three questions!!

Oil leaked from a tank at a rate of r(t) liters per hour. The rate decreased as time passed, and values of the rate at two-hour time intervals are shown in the table. t (h) 0 2 46 10 r(t) (L/h) 8.9 7.9 6.9 6.4 5.7 5.3 Find lower and upper estimates for the total amount of oil (in liters) that leaked from the tank over the interval [0, 10]. (Use five equal subintervals.) lower estimate XL X L upper estimate Enhanced Feedback Please try again. To estimate the volume of oil leaked during an interval of time, find an estimate for the area under the rate-of-leak graph using rectangles. Since the rate is decreasing during the interval, use right endpoints for an underestimate and left endpoints for an overestimate.
