Answer 1

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 2

Answer:

$diameter = 1.4meters \\ radius = 0.7meters \\ circumference \: = 2\pi \: r \\ = 2 \times \frac{22}{7} \times \frac{7}{10} \\ = 4.4meters \\ total \: distance = 1.1km = 1100meters \\ revolutions = \frac{total \: distance}{circumference} \\ = \frac{1100}{4.4 } \\ = 250revolutions$

Hope this will help you.

Remeber the revolution formulae it will help a lot.
