# a bicycle wheel makes 5000 revolutions in moving 11km find diameter of the wheel

70cm  ans..

11km = 1100000 cm

now, circumference = 1100000/5000 = 220

2 x pi x radius = 220

=> radius = 35

=> diameter = 70cm

thumbs up plz...

Find the number of meters in 11 km, divide by 5000
= 2.2 m, is the circumference of the wheel

:
d =
d = .7 meters or 70 cm is the diameter of the wheel
;
:
Check this by finding how far the you go in 5000 rev
= 10.99 ~ 11 km

11km = 1100000cm
circumference= total distance/ revolution=220
2πr =220
on substituting the value we get
r=35cm
d=70cm
