A pie chart is a type of graph that represents the data in the circular graph. The slices of pie show the relative size of the data, and it is a type of pictorial representation of data.

By using the formula,

$Central Angle (θ) = \frac{Percentage of money spent on certain book}{Total percentage of money spent on all books} \times 360 °$

Types of books Percentage( $f_{1}$ ) Conversion of percent to degrees

Fiction $20 ⁒$ $\frac{20}{100} \times 360 = 72 °$

Classic $15 ⁒$ $\frac{15}{100} \times 360 = 54 °$

Sports $10 ⁒$ $\frac{10}{100} \times 360 = 36 °$

Biography $12.5 ⁒$ $\frac{12.5}{100} \times 360 = 45 °$

Magazines $22.5 ⁒$ $\frac{22.5}{100} \times 360 = 81 °$

Others $20 ⁒$ $\frac{20}{100} \times 360 = 72 °$

Therefore, the above shown is the pie chart of the money spent on various types of books by a library in a year.
