Question

how many time does a wheel of radius 28cm rotate to go 5.28m​

Answer 1

Answer:

ans 5,28cm. chota sa answer

Answer 2

Answer:

3

Step-by-step explanation:

Radius = 28 cm

Circumference of the circle = 2πr

= 2 × 22/7 × 28

= 2 × 22 × 4 ( 4 times 7 is 28 , so 28 is cancelled by 7)

= 44×4

= 176 cm

now,

the distance to be covered = 5.28m = 528cm

578/176 = 3

So, the wheel has to rotate 3 times to cover a distance of 5.28 m.

hope this help you.

Thank you.
