| 1) The diameter of a car wheel is 5.6m. Find the distance travelled when it completes 240 revolutions. Answer: 4224m. SOLUTION 1 : Given, Number of revolutions = 240. diameter of the wheel = 5.6m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.8 = 17.6 m. For one revolution, the distance covered = 17.6 m. For 240 revolutions, the distance covered = 17.6 x 240 = 4224 m. |
| 2) The diameter of a car wheel is 9.8m. Find the distance travelled when it completes 160 revolutions. Answer: 4928m. SOLUTION 1 : Given, Number of revolutions = 160. diameter of the wheel = 9.8m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 1.4 = 30.8 m. For one revolution, the distance covered = 30.8 m. For 160 revolutions, the distance covered = 30.8 x 160 = 4928 m. |
| 3) The diameter of a car wheel is 8.4m. Find the distance travelled when it completes 160 revolutions. Answer: 4224m. SOLUTION 1 : Given, Number of revolutions = 160. diameter of the wheel = 8.4m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 1.2 = 26.4 m. For one revolution, the distance covered = 26.4 m. For 160 revolutions, the distance covered = 26.4 x 160 = 4224 m. |
| 4) The diameter of a car wheel is 2.8m. Find the distance travelled when it completes 260 revolutions. Answer: 2288m. SOLUTION 1 : Given, Number of revolutions = 260. diameter of the wheel = 2.8m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.4 = 8.8 m. For one revolution, the distance covered = 8.8 m. For 260 revolutions, the distance covered = 8.8 x 260 = 2288 m. |
| 5) The diameter of a car wheel is 2.8m. Find the distance travelled when it completes 100 revolutions. Answer: 880m. SOLUTION 1 : Given, Number of revolutions = 100. diameter of the wheel = 2.8m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.4 = 8.8 m. For one revolution, the distance covered = 8.8 m. For 100 revolutions, the distance covered = 8.8 x 100 = 880 m. |
| 6) The diameter of a car wheel is 7.7m. Find the distance travelled when it completes 190 revolutions. Answer: 4598m. SOLUTION 1 : Given, Number of revolutions = 190. diameter of the wheel = 7.7m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 1.1 = 24.2 m. For one revolution, the distance covered = 24.2 m. For 190 revolutions, the distance covered = 24.2 x 190 = 4598 m. |
| 7) The diameter of a car wheel is 2.8m. Find the distance travelled when it completes 190 revolutions. Answer: 1672m. SOLUTION 1 : Given, Number of revolutions = 190. diameter of the wheel = 2.8m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.4 = 8.8 m. For one revolution, the distance covered = 8.8 m. For 190 revolutions, the distance covered = 8.8 x 190 = 1672 m. |
| 8) The diameter of a car wheel is 9.8m. Find the distance travelled when it completes 170 revolutions. Answer: 5236m. SOLUTION 1 : Given, Number of revolutions = 170. diameter of the wheel = 9.8m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 1.4 = 30.8 m. For one revolution, the distance covered = 30.8 m. For 170 revolutions, the distance covered = 30.8 x 170 = 5236 m. |
| 9) The diameter of a car wheel is 1.4m. Find the distance travelled when it completes 220 revolutions. Answer: 968m. SOLUTION 1 : Given, Number of revolutions = 220. diameter of the wheel = 1.4m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.2 = 4.4 m. For one revolution, the distance covered = 4.4 m. For 220 revolutions, the distance covered = 4.4 x 220 = 968 m. |
| 10) The diameter of a car wheel is 7m. Find the distance travelled when it completes 100 revolutions. Answer: 2200m. SOLUTION 1 : Given, Number of revolutions = 100. diameter of the wheel = 7m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 1 = 22 m. For one revolution, the distance covered = 22 m. For 100 revolutions, the distance covered = 22 x 100 = 2200 m. |
