Q4 - Pie Charts

4 I decide to draw a pie chart to show the kind of food my weasels enjoy.
a) 30% of my weasels love Cheese (as do I). What angle would I draw to show the Cheese loving weasels on a pie chart? (Remember a pie chart has 360° altogether)
b) The pie chart has a slice with an angle of 24° showing the weasels that enjoy eating batteries. If I have 90 weasels, how many enjoy tasty, tasty batteries? (Hint: think what fraction of the circle 24° is!) (5 marks)
a) 108 degrees
b) 6 weasels
