Circumference of circle = 2*pi*r
Distance covered by circumference of circle = 2*pi*r*15 = 2*pi*24*15
Length not covered by circle(the base of the circle does not touch the end of wall.) = r*2
So distance between X and Y = 2*pi*24*15 + 2*r
Distance covered by circumference of circle = 2*pi*r*15 = 2*pi*24*15
Length not covered by circle(the base of the circle does not touch the end of wall.) = r*2
So distance between X and Y = 2*pi*24*15 + 2*r
