To find: the length of road from point A to E.
Answer to Problem 57E
Explanation of Solution
Given information:
The stretch of roadway is shown by the figure below, where the curves represent the arc of circles.
The values of length of line segment
Calculation:
Let the arc length of AB and CD be
The arc length of AB is evaluated as follows:
Thus the arc length of AB is
The arc length of CD is evaluated as follows:
Thus the arc length of CD is
Now evaluate the length of road from point A to E as shown below.
Thus the length of road from point A to E is
