1 round is = circumference of the wheel
therefore ,
C = 2πr
C = 2*22/7*28
C = 44 * 4
C = 176 m
now in 352 rounds
no.of rotation ,
= 352 / 176
= 2
therefore in 2 rounds the wheel will complete 352 m.

Answer:
Radius of wheel is 28cm.
So, first we will convert 352m into cm
=352×100=35200cm
Now, we will take the circumference.
=2×22/7×28
=44×4
=176
Now, we will divide 35200 to 176
=35200÷176
=200
= 200 times it will rotate.
Hope it helps you.
