Chapter 13, Problem 16T
The environmental effects of a chemical spill in the Clarion River can be estimated from the river's flow volume. To measure this flow volume, it is necessary to find the cross-sectional area of the river at a point downriver from the spill. The distance across the river is 240 feet, and the table gives depth measurements, D(x), in feet, of the river at various distances x from one bank of the river. Use these measurements with Simpsons Rule to estimate the cross-sectional area.
X | 0 | 40 | 80 | 120 | 160 | 200 | 240 |
D(x) | 0 | 22 | 35 | 48 | 32 | 24 | 0 |
