Answer:
The 25-54 age group represents approximately 38.06% of the population in Bangladesh.
Explanation:
To work out the percentage of the population in Bangladesh in the 25-54 age group, we need to find the proportion of the total angle that represents the 25-54 age group in the pie chart.
The angle for the 25-54 age group is given as 137°.
To calculate the percentage, we can use the formula:
Percentage = (angle measure / 360°) * 100
Substituting the given angle measure:
Percentage = (137° / 360°) * 100
Calculating the fraction and converting it to a percentage:
Percentage = (0.3806) * 100 = 38.06%
Therefore, the 25-54 age group represents approximately 38.06% of the population in Bangladesh.
