Question

Diameter of a wheel is 70 cm and it completes 600 revolution in 1 minute. Find its speed

Answer 1

Answer:

700m/s

Step-by-step explanation:

70 * 600/60

= 700m/s

Answer 2

Answer:

22 m/s

Step-by-step explanation:

Hey buddy!!

this is your answer ~

Diameter = 70 cm

Radius, r = Diameter/2 = 35 cm

circumference of the wheel or

distance travelled by the wheel in 1 Revolution = 2 * pi * r = 220 cm = 2.2 m

distance travelled in 600 revolutions = 600*2.2 = 1320 m

time taken, t = 1 min = 60 sec

Speed = distance/time = 1320/60 = 22 m/s
