Quantities in the proportions 1, 4, 6, 7 are to be represented in a pie chart. Calculate the angle of the sector with proportion 7
Answer Details
To calculate the angle of the sector with proportion 7, we first need to find the total of all the quantities in the proportion.
Total quantity = 1 + 4 + 6 + 7 = 18
Next, we need to find the proportion of quantity 7 in relation to the total quantity.
Proportion of quantity 7 = 7/18
To find the angle of the sector that represents this proportion, we need to use the formula:
Angle of sector = Proportion of quantity * 360 degrees
Angle of sector = (7/18) * 360 degrees
Angle of sector = 140 degrees
Therefore, the answer is option D, which is 140 degrees.
