Zorluk: ZorBasic Tools of Economic Analysis

A nation's total federal budget of 500 billion₦500\text{ billion} is allocated across four key sectors: Health (125 billion₦125\text{ billion}), Education (175 billion₦175\text{ billion}), Defense (120 billion₦120\text{ billion}), and Agriculture (the remainder). In a pie chart constructed to represent this budget distribution, what is the central angle (in degrees) representing the allocation for Agriculture?

Cevap: 57.6 degrees

Cevap

The central angle representing the allocation for Agriculture is 57.657.6^\circ.
To calculate the central angle of a sector in a pie chart, find the ratio of that sector's value to the total value and multiply by 360360^\circ. Subtracting the specified sector allocations (125 billion+175 billion+120 billion=420 billion₦125\text{ billion} + ₦175\text{ billion} + ₦120\text{ billion} = ₦420\text{ billion}) from the total budget of 500 billion₦500\text{ billion} leaves 80 billion₦80\text{ billion} for Agriculture. The proportion is 80500=0.16\frac{80}{500} = 0.16. Multiplying 0.160.16 by 360360^\circ results in a central angle of 57.657.6^\circ.

Adım Adım Çözüm

1
Calculate the monetary allocation for the Agriculture sector.
Agriculture allocation = 80 billion₦80\text{ billion}.
The total budget is 500 billion₦500\text{ billion}, and the combined allocation for Health, Education, and Defense is 125+175+120=420 billion₦125 + ₦175 + ₦120 = ₦420\text{ billion}.
2
Find the fractional share of Agriculture relative to the entire budget.
Proportional share = 0.160.16 (or 16%16\%).
Dividing 80 billion₦80\text{ billion} by the total budget of 500 billion₦500\text{ billion} gives 80500=0.16\frac{80}{500} = 0.16.
3
Convert the fractional share into a sector angle in degrees.
Central angle = 57.657.6^\circ.
A full circle in a pie chart corresponds to 360360^\circ, so 0.16×360=57.60.16 \times 360^\circ = 57.6^\circ.
