Answer:
The perimeter of the inside of the track is 444.44 meters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The perimeter of the inside of the track is equal to two times the length of Ā the straight edge plus two times the circumference of a semicircle
Remember that, two times the circumference of a semicircle is the same that the circumference of a circle
so
The perimeter is equal to
[tex]P=2L+\pi D[/tex]
where
[tex]L=150\ m[/tex] ---> the length of straight edge
[tex]D=46\ m[/tex] ----> the diameter of the circle
[tex]\pi=3.14[/tex]
substitute
[tex]P=2(150)+(3.14)(46)=444.44\ m[/tex]
