11 km = 1100000
circumference of wheel = 1100000/5000
=220 cm
circumference = 2πr
220= 2πr
220=2×22/7×r
r= 220×7/2×22
r =35 cm
diameter =2 r
diameter = 2×35
diameter= 70 cm.
Hope its help you....

let the bicycle wheel diameter =x
no revolution = 5000
distance covered =11km
circumference =5000/11
=454.545455
D=C/π=144.69
