Answer» Let the radius of the WHEEL be ‘r’. DISTANCE covered by the wheel in one revolution = 13.2/5000 km = (13200 × 100)/5000 CM = 1320/5cm = 264 cm (? 1 km = 1000 m = 1000 × 100 cm) ⇒ Circumference of the wheel = 264 cm ⇒ 2πr = 264 ⇒ r = 264/2π = 264/(2 × 22/7) = 42 cm ∴ Diameter of the wheel = 2R = 2 × 42 = 84 cm |
