Question

the diameter of a cycle wheel is 28 cm.how many revolution will it make in moving 11 km

Answer 1

Answer:

12500

Step-by-step explanation:

Diameter of wheel = 28 cm

Radius of wheel = $\frac{28}{2}= 14 cm$

Circumference of wheel = $2 \pi r = 2 \times \frac{22}{7} \times 14 = 88 cm$

No. of revolutions in 88 cm(0.00088km)= 1

No. of revolutions in 11 km = $\frac{11}{0.00088}=12500$

Hence No. of revolutions in 11 km is 12500
