diameter = 28 cm
Radius= 14 cm
circumference= 2πr
= 2*22/7*14
= 44*2
=88 cm
No. of revolutions = (352*100)/88
= 400 Revolutions

radius = diameter/2 = 28/2 = 14cm
circumference = 2pirn
35200 = 2×22/7×14×n
n = 246400/616
n = 400
so, the wheel will make 400 revolution to cover distance of 352 meter.
if it seems to be helpful mark me as brainliest.
