Question

DIAMETER OF A WHEEL OF A BUS IS 770CM HOW MUCH DISTANCE WILL IT COVER IN 100 REVELUTION

Answer 1

given , Diameter=770cm

circumference of wheel=πd
=(22/7×770)cm
= 2420cm
distance cover in 1 revolution=2420cm
distance cover in 100 revolution=(100×2420)cm=242000cm

Answer 2

$radius = \frac{diameter}{2} = 385cm(given) \\ \\ let \: us \: assume \: that \\ 1 \: revolution = circumference \: of \: the \: wheel \\ \\ so \: \\ \: \: \: \: \: distance \: covered \: in \: 100 \: revolution \\ = 100 \times 2 \times \pi \times 385 \\ \\ = 242000 \: cm$
