Step-by-step explanation:
3. Circumference of a circle = πd = 22/7 x 0.7 =2.2m
When wheel completes 1 rotation it crosses a distance of 2.2m (1 rotation = 1 circumference)
Total number of rotations = distance/circumference
= 22000/2.2
= 220000/22
= 10000
A wheel completes 10000 rotations to cover the distance of 22km.
4. I'm sorry I don't know this answer
5.Given
Diameter of circle = 14 cm
We know that
Radius r = \(\frac { 14 }{ 2 }\) = 7 cm
Circumference of circle = 2πr
= 2 × \(\frac { 22 }{ 7 }\) × 7
= 44 cm
