Question

5. A racetrack is in the form of a ring whose inner circumference is 528 m and the outer
circumference is 616 m. Find the width of the track​

Answer 1

Answer:

answer is 14.01 m

Step-by-step explanation:

this question based on the consecutive Circle

consecutive Circle are those which has same origin but different radius

here we have to find that difference

let's calculate

given circumference of Circle

inner is 528 m

outer is 616 m

we know that

C of C is 2 pie R

so

2×3.14×R=616 R is for biggest Circle or track

so

R =98.08 m

now for inner track

2×3.14×r=528

r=84.07 m

so thickness of track is R-r=98.08-84.07=14.01 m
