Answer» Step-by-step explanation: 3. Circumference of a circle = πd = 22/7 X 0.7 =2.2m When wheel completes 1 rotation it crosses a distance of 2.2m (1 rotation = 1 circumference) Total number of rotations = distance/circumference = 22000/2.2 = 220000/22 = 10000 A wheel completes 10000 rotations to cover the distance of 22km. 4. I'm SORRY I don't KNOW this answer 5.Given Diameter of circle = 14 CM We know that Radius r = \(\frac { 14 }{ 2 }\) = 7 cm Circumference of circle = 2πr = 2 × \(\frac { 22 }{ 7 }\) × 7 = 44 cm |
