Question

6. A pedestrian underpass is constructed using a cylindrical pipe of radius 2.6 m. The bottom of

Answer 1

Answer:

4.5 m

Step-by-step explanation:

Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m

Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be

$\sqrt {2.6^{2}-1.3^{2}=5.07}=2.25166605$

Approximately 2.25 m

The half width is 2.25 m hence full width will be 2.25*2=4.5 m
