1. A tank has a height of 10 feet. The area of the horizontal cross section of the tank at height h feet is given by
the function A, where A(h) is measured in square feet. The function A is continuous atnd decreases as h
increases. Selected values for A(h) are given in the table above.
(a) Use a left Riemann sum with the three subintervals indicated by the data in the table to approximate the
volume of the tank. Indicate units of measure.
(b) Does the approximation in part (a) overestimate or underestimate the volume of the tank? Explain your
