Statistics – Pie Chart

A pie chart (or a pie graph) is a circular statistical graphical
chart, which is divided into slices in order to explain or
illustrate numerical proportions. In a pie chart, centeral angle,
area and an arc length of each slice is proportional to the
quantity or percentages it represents. Total percentages should
be 100 and total of the arc measures should be 360° Following
illustration of pie graph depicts the cost of construction of a

Cost of construction of a house.

From this graph, one can compare the sum spent on cement, steel
and so on. One can also compute the actual sum spent on each
individual expense. Consider an example, where we want to know
how much more is the labour cost when compared to cost of steel.

$ { Amount spent on labor = frac{90}{60} times 600000 = $
150000 \[7pt] Sum spent on steel = frac{54}{360} times
600000 = $ 90000 \[7pt] Excess = 150000 – 90000 = $ 60000
\[7pt] Let 60000=x% of 600000. \[7pt] implies
frac{x}{100} times 600000 = $ 60000. \[7pt] implies x =
10% of total expense. } $
