(c)
Answer to Problem 105RE
The area of the lot by the model in part(a) is
Explanation of Solution
Given information:
The table shows the measurements(in feet) of a lot bounded by a stream and two straight roads that meets at right angles(see figure).
0 |
Calculation:
As found in part(a), the model for the data is
The area of the curve bounded between
Further simplify,
Therefore, the area of the lot by the model in part(a) is
