Question

To show the distribution of proteins and other dry elements in the human body, the arc of the circle should subtend at the centre an angle of:

• A. ${54}^o$
• B. ${126}^o$
• C. ${108}^o$
• D. ${252}^o$

Answer 1

The correct option is C ${108}^o$

Percentage of proteins and other dry elements in the body = (16% + 14%)
= 30%.
$\therefore$ Central angle corresponding to proteins and other dry elements together $=30$
$={108}^o.$
