Question

How many times a wheel of radius 28cm
must rotate to go 352m ? Take (pie as 22/7)​

Answer 1

Answer:

The circumference of a wheel of 28 cm radius = 2(pi)r = 2*22*28/7 = 176 cm or 1.76 m. So in order to cover a distance of 352 m the wheel has to rotate 352/1.76 = 200 times.

Answer 2

Step-by-step explanation:

The circumference of a wheel of 28 cm radius = 2(pi)r = 2*22*28/7 = 176 cm or 1.76 m. So in order to cover a distance of 352 m the wheel has to rotate 352/1.76 = 200 times.
