Answer:
400 revolutions
Step-by-step explanation:
radius of well =28 cm
therefore, distance travelled in one revolution or circumference= 2πr
=2*22/7*28 cm
=176cm
1 metre =100cm
therefore, 176cm =176/100 metre
=1.76metre
total distance given =704metre
therefore, number of revolutions=704/1.76
=400 revolutions
