Answer:
- d)40 revolution is the required answer.
Step-by-step explanation:
According to the Question
It is given that,
- Radius of Circular Wheel ,r = 0.7m
- Rolling distance ,d = 176m
we have to calculate the number of revolution made by given wheel in rolling distance of 176 m.
- No. of Revolution = Total Distance Covered/Circumference of the wheel
by putting the value we get
↠ No. of Revolution = 176/2πr
↠ No. of Revolution = 176/2×22/7 × 0.7
↠ No. of Revolution = 176/ 44×0.1
↠ No. of Revolution = 176/4.4
↠ No. of Revolution = 40
- Hence, the number of revolution made by the circular wheel is 40 .
