Question

Pls find with explanation?

afterwards ,he/she will given brainliest

Answer 1

Radius of outer track = (Outer Circumference) / 2π = 440 * 7 / (2 * 22) = 70m

Radius of inner track = (Inner Circumference) / 2π = 220 * 7 / (2 * 22) = 35m

Width = Outer Radius - Inner Radius = 35m

Mark my answer as BRAINLIEST please.

Answer 2

Hey mate... Here's your answer

Given:
We know that,
Circumference of a circle=2πr units

Inner circumference of the track=220m

2πr=220

r=220×7/22 × 1/2

(Inner radius)r=35m

Outer circumference of the track=440m

2πR=440

R=440 × 7/22 × 1/2

(Outer radius)R=70m

Width of the track =. Outer radius - Inner radius

=70 - 35

=35m

Therefore width of the track = 35 m

Hope it helps you
