Concept use:
Proportion of a Particular Item $=($ Number of Particular Items $)∕($ Total number of Items $)$
Angle of sector representing Particular Item $=$ Proportion of Item $\times 360^{\circ }$
Explanation:
Given:
Number of mangoes $=44$
Number of apples $=56$
Number of oranges $=42$
Number of guavas $=30$
Number of pomegranates $=38$
Total number of fruits $=44+56+42+30+38=210$
Now, to find the proportion of apples:
Proportion of apples $=($ Number of apples $)∕($ Total number of fruits)
$=56∕210$
To find the angle of the sector representing apples, we'll multiply this proportion by 360 degrees (the total degrees in a circle):
Angle of sector representing apples $=$ Proportion of apples $\times 360$ degrees
$=56∕210\times {360}^{\circ }$
$={96}^{\circ }$
So, the angle of the sector representing apples in the pie chart will be 96 degrees.
