Question

A radius of a circular wheel is 3.5m .how many revolutions will it make in travelling 11 km

Answer 1

circumstance of circle = 2 × pie × radius
= 2 × 22 ÷ 7 × 3.5 = 22 meters
11 km = 11000 meters
revolution = 11000÷22 = 500

Answer 2

HELLO FRIEND,
I HOPE THIS ANSWER HELPS YOU.

SO, LET'S START,,
radius of a circle=3.5m.
distance of travelling=11km
Circumference=2πr
=2×22/7×3.5
=22m.

The distance of travelling in m=11×1000
=11000m.

SO, the revolutions are=11000÷22
=500.
So, the revolutions are 500.

PLEASE MAKE THIS ANSWER AS THE BRAINLIEST ANSWER IF IT IS HELP YOU.

I AM FEEL PROUD TO GIVE YOUR ANSWER.


THANK YOU.......................
