|
Karanj | Behada | Arjun | Bakul | Kadunimb |
| No. of trees | 20 | 28 | 24 | 22 | 26 |
Solution
Total number of trees planted = 120
Measure of central angle (θ) = `"Number of scores in the components"/"Total number of scores" × 360°`
| Tree Name | Number of tress | Central Angle |
| Karanj | 20 | `20/120×360=60°` |
| Behada | 28 | `28/120×360=84°` |
| Arjun | 24 | `24/120×360=72°` |
| Bakul | 22 | `22/120×360=66°` |
| Kadunimb | 26 | `26/120×360=78°` |
| Total | 120 | 360° |
