Complete Question

Draw a pie chart for the percent of the money spent on various types of books by a library in a year.

Type of book | %

Fiction | 20%

Classics | 15%

Sports | 10%

Biography | 12.5%

Magazines | 22.5%

Others | 20%

Solution

A pie chart is a graphical representation of a set of numerical data which comes in a circular shape divided into slices, with the size of each slice corresponding to the proportion of the numerical data it represents.

Because it is a circle, the total angles in a pie chart is 360°.

The angles are divided into slices with the size of each slice corresponding to how large the data it represents is.

So, we first convert the data given into degrees.

Since the data is given in percentage, for each of the groups, the conversion from percentage will be

Angle = (Proportion) × 360°

Type of book | % | Angle

Fiction | 20% | 72°

Classics | 15% | 54°

Sports | 10% | 36°

Biography | 12.5% | 45°

Magazines | 22.5% | 81°

Others | 20% | 72°

Hope this Helps!!!

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
