Question

the radius
of a bicycle is 35 cm find the distance the bicycle travel if its wheels make 100 revolutions ​

Answer 1

Answer:

RADIUS = 35 CM

NOW,

CIRCUMFERENCE = DISTANCE TRAVELLED IN 1 REVOLUTION

SO,

CIRCUMFERENCE = 2πR

= 2*22/7*35

= 2*22*5

= 220 CM

TOTAL REVOLUTIONS = 100

THEREFORE, DISTANCE TRAVELLED = CIRCUMFERENCE* NO. OF REVOLUTIONS

DISTANCE TRAVELLED = 220*100

= 22000 CM

= 220 M

= 0.22 KM
