How many times a wheel of radius 28cm must rotate to go 352m? ( Take ∏= 22/7) 13 Convert the following a) 3 ha in 2 b) 10002 in 2
Answers
Answer:
The wheel will make 200 revolution to cover 352m distance .
Step-by-step Explanations :
Given: Radius of wheel (R) = 28cm
To find : How many Revolution will the wheel make to travel 352m = ?
Radius of wheel (R) = 28cm -------- ( given )
We know that,
Circumference of wheel = 2πR
Substituting the given value in above formula we get,
Circumference of wheel = 2 × 22/7 × 28
= 176cm
= 1.76m ------------( since 1m = 100cm )
So, 1.76m is the Distance covered by wheel in 1 revolution.
Therefore the total number of revolution it takes to cover 352m is ,
No of revolution = total distance / distance covered in 1 revolution
Substituting the values in above formula we get,
No of Revolution = 352/1.76
= 200
Hence the wheel will make 200 revolution to cover 352m distance .
