Draw a pie chart for the percent of money spent on various types of books by a library in one year. Type of book Fiction Classics Sports Biography Magazines Others % 20 % 15 % 10 % 12 . 5 % 22 . 5 % 20 %

Given, the table of data that spent on various types of books by a library in one year, Type of book Fiction Classics Sports Biography Magazines Others % 20 % 15 % 10 % 12 . 5 % 22 . 5 % 20 % We should draw pie chart for the above data, 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 ) = Percentage of money spent on certain book Total percentage of money spent on all books × 360 ° Types of books Percentage( f 1 ) Conversion of percent to degrees Fiction 20 ⁒ 20 100 × 360 = 72 ° Classic 15 ⁒ 15 100 × 360 = 54 ° Sports 10 ⁒ 10 100 × 360 = 36 ° Biography 12 . 5 ⁒ 12 . 5 100 × 360 = 45 ° Magazines 22 . 5 ⁒ 22 . 5 100 × 360 = 81 ° Others 20 ⁒ 20 100 × 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.

The pie chart shows how a pupil spends his/her time in a Maths lesson which lasts 60 minutes. How much time does he/she spend: getting ready to work

Given, The central angle for getting ready to work is 48 ° We should find the time spent for getting ready to work, Time spent = Percentage spent for getting ready to work 360 ° × Total time = 48 360 × 60 = 8 Therefore, the time spent for getting ready to work is 8 minutes.

The pie chart shows how a pupil spends his/her time in a Maths lesson which lasts 60 minutes. How much time does he/she spend: sharpening pencil?

Given, The central angle for sharpening pencil is 60 ° We should find the time spent for sharpening pencil, Time spent = Percentage spent for sharpening pencil 360 ° × Total time = 60 360 × 60 = 10 Therefore, the time spent for sharpening pencil is 10 minutes.

The pie chart shows how a pupil spends his/her time in a Maths lesson which lasts 60 minutes. He/she spends 3 minutes working. What is the angle on the pie chart for the time spent working?

Given, The time spent for working is 3 minutes. We should find the time spent for working, Central angle ( θ ) = Time spent for working Total time spent for all the works × 360 ° = 3 60 × 360 ° = 18 Therefore, the time spent for work is 18 minutes.
