Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.

The first one answer is for a different equation. I have this test and got to FLVS. This is the right answer.
Step-by-step explanation:
SInce the length is 150 on one side you multiply it twice. 150*2=300
Then you find the circumference which is 46.
Then, you solve 80+46(3.14)
You multiply 46*3.14= 144.44.
Then you add 144.44 to 300 which gets you 444.44
