The second one.
10 km is greater.
10 km
it is but obvious 50 km > 139 cm 1 km=100000 cm
Much less than 2 km. 9000 cm is no more than 300 feet.
2 km is greater.
Yes, it is.
The conversion between cm and km are given .On finding the relation we get as follows . we will get , 1 km =100000 cm. 6 km =600000 cm. that is greater than 600 cm.
The second one.
For determining which is the bigger unit we have to relate both the units to each other . we know, 1 km =100000 cm. 2 km =200000 cm which is greater than 9000 cm.
10 km is greater.
2 km. 74000 cm = 0.740 km, and 82400 mm = 0.0824 km.
No, it is not.
Yes, very much greater than 100 cm
No, a centimeter is 100,000 times smaller than a kilometer.
Yes
42205 cm is less than 4556 km42205 cm < 4556 km
