Let inner radius =r
And outer radius =R
Now it is given that
2pai R=616m
R=616*7/2*22
R=98m
And 2pai r=528m
. r=528*7/44= 84m
Width of the track =R-r=98-84= 14m
And outer radius =R
Now it is given that
2pai R=616m
R=616*7/2*22
R=98m
And 2pai r=528m
. r=528*7/44= 84m
Width of the track =R-r=98-84= 14m
