the wheel of a bullock cart has a diameter of 1.4m.how many rotations will the wheel complete as the cart travels 1.1km
Answers
Answer:
please mark me as the brainliest
Step-by-step explanation:
Diameter of the wheel of the bullock cart (d) = 1.4 m Circumference of the wheel of the bullock cart (c) = πd = 22/7 x 1.4 = 22/7 x 14/10 = 44/10 = 4.4m Distance corvered in 1 ratation = Circumference of the wheel = 4.4 m Number of rotatiuons = (Distance covered)/ circumference = (1.1 km)/4.4m = (1.1 x 1000m)/4.4m ...[1 km = 1000m] = (11 x 1000)/44 = 250 The wheel of the bullock cart will compleate 250 rotations as the cart travels 1.1 km.Read more on Sarthaks.com - https://www.sarthaks.com/861674/the-wheel-bullock-cart-diameter-how-many-rotations-will-the-wheel-complete-the-cart-travels
☆Answer ☆
Diameter of cart =1.4m
Circumference =πd=
7
22
×1.4
=22×0.2
=4.4 metres
1 rotation of the wheel travels 4.4 metres.
Total distance to travel =1.1km =1100m
No. of rotations required =
4.4
1100
=
44
11000
=250
The wheel completes 250 rotations to reach 1.1km.
