Diameter of wheel car= 28cm
Radius= D/2 = 28/2 = 14cm
Distance covered by wheel in one revolution = Circumference of wheel = 2πr
= 2×22/7×14 = 44×2 = 88cm
DISTANCE COVERED BY WHEEL IN 1 REVOLUTION = 88 CM
THEREFORE,
DISTANCE COVERED BY WHEEL IN 5000 REVOLUTIONS = 5000×88 = 440000 cm²
Radius= D/2 = 28/2 = 14cm
Distance covered by wheel in one revolution = Circumference of wheel = 2πr
= 2×22/7×14 = 44×2 = 88cm
DISTANCE COVERED BY WHEEL IN 1 REVOLUTION = 88 CM
THEREFORE,
DISTANCE COVERED BY WHEEL IN 5000 REVOLUTIONS = 5000×88 = 440000 cm²
