More the value of quantity, more will be the area or central angle it will cover in pie-chart.
Arrange the food items in descending order as per the value of protein obtained from it.
⇒ Oranges > Carrot or Beans > Tomatoes > Cucumber
⇒ Angle covered by oranges = 1260 [Green region],
Angle covered by carrot = 720 [Violet/Blue region],
Angle covered by beans = 720 [Blue/Violet region],
Angle covered by tomatoes = 540 [Red region], and
Angle covered by cucumber = 360 [Purple region],
∴ The regions corresponding to tomatoes and cucumbers in pie-chart are red and purple respectively.
