Question

If the radius of the wheel of a cart is 38.5 cm. How many revolutions of the wheel are required to travel a distance of 145.2 meters?

​

Answer 1

Answer:

Radius=38.5cm

Circumference of wheel=2πr

=2*22/7*38.5

=2*22*5.5

=22*11

=242 cm

No.of revolutions to travel 145.2m=145.2m/242cm

=145.2*100cm/

242cm

= 14520/242

=7260/121

=60

Therefore, No. of revolutions of the wheel

required to travel 145.2 meters. = 60
