Question

The following pie chart gives the distribution of constituents in the human body. The central angle of the sector showing the distribution of protein and other constituents is

Protein 16%

• A. ${108}^0$
• B. ${54}^0$
• C. ${30}^0$
• D. ${216}^0$

Answer 1

The correct option is A

${108}^0$

Pie chart:

The distribution of protein constituents in the body$=16\%$

The distribution of other constituents in the body $=14\%$

The total distribution of protein and other constituents in the body $=16\%+14\%=30\%$

$$\begin{gathered} =\left(\frac{30}{100}\right)\times {360}^0 \\ ={108}^0 \end{gathered}$$

Therefore, the central angle of the sector shows the distribution of protein and other constituents is ${108}^0$.
