Question

evolution the diameter of a wheel is 28 cm how many Revolution will it make to travel 352 m

Answer 1

r=d/2
=28/2
=14
1 revolution=2*22/7*14=88
no of revolution made=100/88=1.366

Answer 2

Answer:

Step-by-step explanation:

Diameter of wheel= 28 cm.

Therefore radius of the wheel= 28/2

=14 cm

Circumference of the wheel=2πr

= 2×22/7×14

= 88 cm.

In metre= 88/100

= 0.88 m

= 352/0.88

=400 m.
