| 10) The diameter of a car wheel is 4.9m. Find the distance travelled when it completes 270 revolutions. ___m. Answer:_______________ |
| 1) The diameter of a car wheel is 9.8m. Find the distance travelled when it completes 250 revolutions. Answer: 7700m. SOLUTION 1 : Given, Number of revolutions = 250. 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 250 revolutions, the distance covered = 30.8 x 250 = 7700 m. |
| 2) The diameter of a car wheel is 8.4m. Find the distance travelled when it completes 280 revolutions. Answer: 7392m. SOLUTION 1 : Given, Number of revolutions = 280. 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 280 revolutions, the distance covered = 26.4 x 280 = 7392 m. |
| 3) The diameter of a car wheel is 2.1m. Find the distance travelled when it completes 210 revolutions. Answer: 1386m. SOLUTION 1 : Given, Number of revolutions = 210. diameter of the wheel = 2.1m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.3 = 6.6 m. For one revolution, the distance covered = 6.6 m. For 210 revolutions, the distance covered = 6.6 x 210 = 1386 m. |
| 4) 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. |
| 5) The diameter of a car wheel is 4.2m. Find the distance travelled when it completes 270 revolutions. Answer: 3564m. SOLUTION 1 : Given, Number of revolutions = 270. diameter of the wheel = 4.2m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.6 = 13.2 m. For one revolution, the distance covered = 13.2 m. For 270 revolutions, the distance covered = 13.2 x 270 = 3564 m. |
| 6) The diameter of a car wheel is 2.1m. Find the distance travelled when it completes 150 revolutions. Answer: 990m. SOLUTION 1 : Given, Number of revolutions = 150. diameter of the wheel = 2.1m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.3 = 6.6 m. For one revolution, the distance covered = 6.6 m. For 150 revolutions, the distance covered = 6.6 x 150 = 990 m. |
| 7) The diameter of a car wheel is 4.2m. Find the distance travelled when it completes 160 revolutions. Answer: 2112m. SOLUTION 1 : Given, Number of revolutions = 160. diameter of the wheel = 4.2m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.6 = 13.2 m. For one revolution, the distance covered = 13.2 m. For 160 revolutions, the distance covered = 13.2 x 160 = 2112 m. |
| 8) The diameter of a car wheel is 2.1m. Find the distance travelled when it completes 280 revolutions. Answer: 1848m. SOLUTION 1 : Given, Number of revolutions = 280. diameter of the wheel = 2.1m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.3 = 6.6 m. For one revolution, the distance covered = 6.6 m. For 280 revolutions, the distance covered = 6.6 x 280 = 1848 m. |
| 9) The diameter of a car wheel is 9.8m. Find the distance travelled when it completes 140 revolutions. Answer: 4312m. SOLUTION 1 : Given, Number of revolutions = 140. 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 140 revolutions, the distance covered = 30.8 x 140 = 4312 m. |
| 10) The diameter of a car wheel is 4.9m. Find the distance travelled when it completes 270 revolutions. Answer: 4158m. SOLUTION 1 : Given, Number of revolutions = 270. diameter of the wheel = 4.9m Distance covered in one revolution = Circumference of wheel circumference of wheel = πd = x = 22 x 0.7 = 15.4 m. For one revolution, the distance covered = 15.4 m. For 270 revolutions, the distance covered = 15.4 x 270 = 4158 m. |
