distance between centres of both rollers= 22+21+21=64
length of belt not in contact of rollers= 64 cm
circumference of roller= 2πr
=2*(22/7) 21=132 cm
length of bet covered on one roller = circumference/2 = 132/2 = 66cm
length of belt on both rollers= 66+66 = 132 cm
total length of belt= 132+64 = 196 cm
