Radius of Wheel = 42 cm

Note -

♢ Π = pi = 22 / 7

Circumference of the Wheel

= 2Πr

= [ 2 × 22 / 7 × 42 ] cm

= [ 2 × 22 × 6 ] cm

= 264 cm

Distance travelled by the Wheel

= 19.8 km

= (19.8 × 100,000) cm

= 1,980,000 cm

Therefore,

Number of Revolutions by the Wheel

= Distance travelled by the Wheel / Circumference of the Wheel

= 1,980,000 cm / 264 cm

= 1,980,000 / 264

= 7,500


Hence, the Wheel will take 7,500 complete revolutions in a journey of 19.8 km
