Answer:

The diameter of the track is 49 m.

Explanation:

The circumference of the track = 154 m

The Circumference of a Circle = 2 π r

⇒
2 * (22)/(7) * r = 154

⇒
r = (154 * 7)/(2 * 22) = 24.5

or, radius of the circle = 24.5 m

Now, Diameter = 2 x Radius

or, Diameter = 2 x 24. 5 m

= 49 m

Hence, the diameter of the track is 49 m.
