i have a pie chart that i need to complete. However, it is all in percentages and i need to covert those percentages in to numbers to work out the total number and draw the pie chart.
Water usage percentage decimal×360° = central angle
laundry 20% .20×360° = 72°
Toilet flushing 30% .30×360° = 108°
Kitchen and drinking 10% .10×360° = 36°
Shower and bath 35% .35×360° = 126°
Cleaning 5% .05×360° = 18°
------------------------------------------------------------------
100% 360°
Be sure to measure those central angles with a protractor.
