A pie diagram shows the percentage distribution of proteins, water and other dry elements in the human body. Given that proteins corresponds to 16% and water corresponds to 70% . If both proteins and the other dry elements corresponds to p% , then what is the central angle of the section representing p on the pie diagram?
- A54°
- B96°
- C108°Correct
- D120°
Explanation
Here's a brief explanation:
-
Calculate the percentage of "other dry elements": Total percentage = 100% Proteins = 16% Water = 70% Other dry elements = 100% - (16% + 70%) = 100% - 86% = 14%.
-
Calculate p%: p% = Proteins + Other dry elements = 16% + 14% = 30%.
-
Convert p% to a central angle: A full circle represents 360 degrees, which corresponds to 100%. Central angle = (Percentage / 100) * 360 degrees Central angle for p = (30 / 100) * 360 degrees = 0.30 * 360 degrees = 108 degrees.
Therefore, the central angle representing p is 108 degrees.
The final answer is C) 108 degrees.
