Question

Diameter of a wheel is 7m to covered 22km distaice how many revolution take by wheel

Answer 1

Answer:

484

Step-by-step explanation:

diameter = 7 meter

circumference = 22/7 * d = 22/7 * 7 =22 m

now revolutions = 22 km * 22m

= 484

hope it helps

Answer 2

Answer:

Step-by-step explanation:

Given,

Diameter=7 m. [D]

Circumference=2⚻r=⚻×2r=⚻D=(22/7)×7 m=22 m

Therefore Number of revolutions=Distance÷Circumference=22 km÷22 m=22000 m÷22 m=1000 revolutions
