Question

the inner and outer circumference of a circular track 462 and 484 respectively calculate the width of the track.​

Answer 1

Answer:

The inner and the outer radii of a circular track are 7 m and 14 m, respectively. Find the cost of levelling the track at the rate of ...

Answer 2

Answer:

Width = 3.5 units

Step-by-step explanation:

Given,

Inner Circum. = 462

πd₁ = 462

d₁ = 462/π        

Outer Circum. = 484

πd₂ = 484

d₂ = 484/π

Now,

Width of the track = (d₂ - d₁)/2

                              = (484 - 462)/2π

                              = $\frac{22*7}{2*22}$

                             = 7/2 = 3.5
