Answer 2

Answer:

7 m

Step-by-step explanation:

Let r₁ and r₂ be the outer radii of the ring.

(i)

Given outer circumference is 396 m.

⇒ 2πr₁ = 396

⇒ 2 * (22/7) * r₁ = 396

⇒ 44₁ = 2772

⇒ r₁ = 63 m.

(ii)

Given, Inner circumference = 352 m.

⇒ 2πr₂ = 352

⇒ 2 * (22/7) * r₂ = 352

⇒ 44r₂ = 2464

⇒ r₂ = 56 m.

∴ Width of the track = (63 - 56) m = 7 m
