If the radius is 53cm then the circumference of the wheel is 2(pi)(53) which is appoximately 333cms (or 3.33 metres)
so the wheel can roll 16/3.33 times which is 4.80.
But since you ask about complete revolutions then the answer is 4.

-The first thing you have to do is convert all the unit into one. In this case, convert into cm is the best way to do
16m=1600cm
-Then you have to find the circumference of the wheel because it roll on the surface of the street, so we don't need to find the area, just the circumference is enough
-the formula is C=2*pi*radius
C=2*3.14*53
C=332.84 cm
Then you need to divide the distance (1600cm) by the circumference (332.84)
revolution=1600/332.84
=4.8 revolutions
You can keep the 4.8 or either round it up or down, or both just to make sure ;)

C = 2 Ï r
C = 2 x Ï x 53 cm
C = 333 cm (1 revolution)
Rolls 1600 cm
No. of revolutions = 1600 / 333 = 4.8
It will make 4 complete revolutions.
