Question

A car dealer wants to draw a Pie Graph representing the different types of cars he sold in a given month. He sold a total of 90 this month with 15 of those cars being convertables. How many degrees should be used to represent convertables in the Pie Graph? (You do not have to use the degree symbol in your answer.)

Answer 1

60°

Explanation:

Here we are given that the number of convertibles cars. Total number of cars owned by the dealers is 90. We have to draw the pie graph for above ratio. The pie chart is a circular statistical graph , where the different portion in form of sectors on the circle showing the amount of different entities.

The angle covered by an entity is in the same proportion as its number is in ration to the total number of all the entities.

Hence

`(15)/(90)=(\theta)/(360)\\\\\theta=(15*360)/(90)\\\theta=(15*4)/(1)\\\theta=60\\`

Hence we will represent 60 degrees in order to represent 15 cars in our chart.
