Question

bicycle been made 500 Evolutions in 11 kilometre find the diameter of the wheel​

Answer 1

11 km equates to 500 revolutions. So each revolution is 11000m/5000 = 2.2m , which is the circumference. Since, a wheel move by the distance equal to it's circumference in one revolution. ... Hence, Diameter of wheel is 0.70m or 70 cm .

Answer 2

Answer:

0•70 metre

Step-by-step explanation:

5000×circumference=11km (convert 11 km into metre) 11000metre

5000×2πr=11000m

(cut 5000/11000 and then multiply 5×2=10)

10×22/7×r = 11

Radius= 11×7 =

10×22 = 0•35m

diameter=2×radius= 0•35×2 = 0•70metre
