Question

the diameter of a cycle wheel is 70 cm,how far will it go in 24 revolutions

Answer 1

Diameter of wheel = 70 cm


Radius of wheel = 30 cm .



Area covered by wheel in 1 revolution = Circumference of wheel = 1/2 πR² = 1/2 × 22/7 × 30 × 30 = ( 22 × 15 × 30 ) / 7 = 9900 /7 cm².


Distance covered by wheel in 24 revolutions = 24 × ( 9900/7 ) = 237600 / 7 = 33942.85 cm².
