circumference=2*pi*d/2
=22/7*7/22*2
4000/2=2000

Gaurav Verma 9 years AGO

diameter = 7/11
circumference = PI * D = 7/11 * 22/7 = 2M
DISTANCE = 4 km = 4000m
no of rounds = 4000/2= 2000

Radius=d/2=7/22m.
(circumference of wheel)�(no. of turns)=4000m
(2?r)�n=4000
(2�22/7�7/22)�n=4000
n=2000.

ANKUR BAJWA 9 years AGO

r=7/22
1 round=2*22/7*r=2*22/7*7/22=2m
total distance=4 km=4000 m
total rounds=4000/2=2000 rounds

Like? Yes (6) | No (6)

Moumita Choudhury 9 years AGO

Number of rounds = Circumference/Distance Covered
(4000*2*11*7)/(2*7*22) = 2000

Like? Yes (7) | No (10)

Devendra Marghade 9 years AGO

Number of rounds=Distance/Perimeter=4000/(Pi*Diameter)
=4000/[(22/7)*(7/11)]
=2000
