Answer:

The diameter of the track is 49 m.

Step-by-step explanation:

The circumference of the track = 154 m

The Circumference of a Circle =  2 π r

⇒[tex]2 \times \frac{22}{7}  \times r = 154[/tex]

⇒[tex]r = \frac{154  \times 7}{2 \times 22}  = 24.5[/tex]

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.
