Question

A bicycle wheel makes 5000 revolution's in moving 11 km. find the diameter of the wheel.

Answer 1

Heya !!




Distance covered by the wheel in 1 revolution = ( 11 × 1000 × 100 ) / 5000



=> 220 cm.



Therefore , circumference of the wheel = 220 cm.




Let diameter of the wheel be D cm.


Then , πD = 220



=> D = 220 × 7/22 )



=> D = 70 cm.



Hence,

The diameter of the wheel is 70 cm.

Answer 2

bicycle wheel makes 5000 revolution in moving 11 km. find the diameter of the wheel.
:
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
