Problem No. 1 :
• Calculate the total amount by adding all the items' cost.
Total amount
= 3200 + 2400 + 1200 + 1200 + 800 + 800
= 9600
• Find proportion of each item as follows.
Rent = = 0.33
Food = = 0.25
Clothing = = 0.125
Education = = 0.125
Entertainment = = 0.083
Saving = = 0.083
• Calculate the angle between the two sides of each pie slide.
Rent = 0.33 * 360° = 118.8°
Food = 0.25 * 360° = 90°
Clothing = 0.125 * 360° = 45°
Education = 0.125 * 360° = 45°
Entertainment = 0.083 * 360° = 29.88°
Saving = 0.083 * 360° = 29.88°
• Draw a circle using a compass and draw a radius to it.
• Put the protractor on the circle's radius and keep drawing angle sections for each pie slice.
• Finally when the drawing is finished, you may proceed to colourise.
• See the first photo.
Problem No. 2 :
• Calculate the total no. of hours by adding all the activities.
Total no. of hours
= 8 + 8 + 1 + 3 + 4
= 24
• Find proportion of each activity as follows.
School = = 0.33
Sleeping = = 0.33
Playing = = 0.041
Studying = = 0.125
Others = = 0.17
• Calculate the angle between the two sides of each pie slide.
School = 0.33 * 360° = 118.8°
Sleeping = 0.33 * 360° = 118.8°
Playing = 0.041 * 360° = 14.76°
Studying = 0.125 * 360° = 45°
Others = 0.17 * 360° = 61.2°
• Draw a circle using a compass and draw a radius to it.
• Put the protractor on the circle's radius and keep drawing angle sections for each pie slice.
• Finally when the drawing is finished, you may proceed to colourise.
• See the second photo.
Problem No. 3 :
• Draw two rectangular axes ( x axis horizontally and y axis vertically ).
• Label the axes with favourite subjects and their respective students.
• Draw bars as high / long as you need them to. { Like, Chemistry is favourite to 25 students, so draw the bar upto the 24 labelled mark. }
