The perimeter of the inside of the track is 435.84 m.
Given
A running track in the shape of an oval is shown.
The ends of the track form semicircles.
The diameter of the shape is 56.
What is the circumference of a circle?
The circumference of the circle is equal to two times of radius.
The perimeter of the circle is;
[tex]\rm Perimeter=2\pi r\\\\Perimeter = 2\pi \times \dfrac{diameter}{2}\\\\Perimeter = \pi \times diameter\\\\Perimeter= \pi \times 56\\\\Perimeter= 3.14 \times 56\\\\Perimeter= 175.84[/tex]
The length of the inside of the track is given as 130 m, and there are 2 sides is;
= 130 + 130 = 260m
Therefore,
The perimeter of the inside of the track is;
The perimeter of the track = length inside track + perimeter of the circle.
The perimeter of the track = 260 + 175.84
The perimeter of the track = 435.84 m
Hence, the perimeter of the inside of the track is 435.84 m.
