Question

who much distance cover by 40cm dia wheel in one revolvaton

Answer 1

the distance covered is 10 cm

Answer 2

AS WE KNOW DISTANCE COVERED BY A WHEEL IN ONE REVOLUTION = 1*2πr

HERE WE HAVE -

DIAMETER = 40 CM

RADIUS = 20 CM [40/2]

--------------------------------

DISTANCE TRAVELED BY WHEEL IN ONE REVOLUTION = [1]*[2]*[3.14]*[20]

= [2*314*20]/100

= [2*314*2]/10

= [314*4]/10

= 1256/10

= 125.6 CM            or 1.256 meters

Hope You Understand

Thank You
