A running track in the shape of an oval is shown. The ends of the track form semicircles.What is the perimeter of the inside of
the track? (π = 3.14) 260.00 m 347.92 m 372.00 m 435.84 m

Answer:
435.84 is the answer.
Step-by-step explanation:
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.
