Question

A wheel,14 cm in diameter,make 3000 revolution per minute.Find the speed m/sec.​

Answer 1

Answer:

1100

Step-by-step explanation:

circumference of the circle =2 x pi x r

2 x 22/7 x7 = 44cm

total distance = 44 x 3000

                       = 132000 cm

                        = 1320 m

speed              = D/T

                        = 1320/60

                        = 22 m/s
