Question

If a tiers radius is 35cm and it takes 60 revolutions per min calculate the distance it covers in kms​

Answer 1

Answer:

0.0022 Km

Step-by-step explanation:

radius= 35 cm

no. of revolution per minute= 60

there are 60 seconds in 1 minute so, number of revolution in 1 second= 60/60= 1

now, distance covered in 1 revolution= circumference of circle

distance covered= 2 × 22/7 × 35

distance covered= 2 × 22 × 5

distance covered= 44 × 5

distance covered = 220 cm

distance covered in kms= 0.0022 km (1 cm= 0.00001 km)
