Question 1 Report
The table here shows the sectoral allocation of a country's budget. Illustrate the data accurately with a pie-chart. Show your workings clearly.
| Sector | Amount (N million) |
| Health | 30 |
| Education | 25 |
| Housing | 15 |
| Manufacturing | 10 |
| Agriculture | 20 |
Each sector angle is \(\dfrac{\text{sector amount}}{\text{total}}\times360^\circ\). The total allocation is \(30+25+15+10+20=100\) million naira.
| Sector | Amount (N m) | Angle | Percentage |
|---|---|---|---|
| Health | 30 | \(\frac{30}{100}\times360=108^\circ\) | 30% |
| Education | 25 | \(\frac{25}{100}\times360=90^\circ\) | 25% |
| Housing | 15 | \(\frac{15}{100}\times360=54^\circ\) | 15% |
| Manufacturing | 10 | \(\frac{10}{100}\times360=36^\circ\) | 10% |
| Agriculture | 20 | \(\frac{20}{100}\times360=72^\circ\) | 20% |
The angles sum to \(108+90+54+36+72=360^\circ\), so the pie chart is drawn with these five sectors.
