Question

distance of 11 kilometre the wheel of a car makes 5000 Revolution find the radius of the wheel​

Answer 1

Answer:

35 cm (approx)

Step-by-step explanation:

Distance travelled = number of revolutions × circumference of wheel

⇒ 11 km = 5000 × circumference

⇒ circumference = 11 km / 5000 = 11000 m / 5000 = 11/5 m = 2.2 m = 220 cm

⇒ 2π × radius = 220 cm

⇒ radius = 220 cm / 2π  =  110/π cm ≈ 35 cm.

Hope this helps.

Answer 2

Step-by-step explanation:

n×πd=11km

5000×22/7×d=11000m

10d=7

d=7/10

r=d/2

7/10/2

7/20m
