Most likely a bar or pie graph
Line Graph.
a collumn graph
probably orographic bar graph would work the best!
A histogram
Anyone of them is fine. It doesn't really matter.
In a circle graph, also known as a pie chart, the total degrees in a circle is 360. To calculate the degrees for 75.6 in a circle graph, you would use the formula: (75.6 / 100) * 360 = 271.44 degrees. Therefore, 75.6 in degrees on a circle graph would be approximately 271.44 degrees.
The type of graph you would use would be a PICTURE GRAPH or a TALLY CHART
line graph
A stacked bar graph would be a suitable choice to display the amount of iron ore in four different countries. This graph allows you to compare the total amount of iron ore in each country as well as the distribution of iron ore production within each country.
Line Graph.
Most likely a bar or pie graph
If, by circle graph, you mean a pie graph then 450 will be 360*450/n degrees where n is the sum of all the sectors of the pie.
circle graph
circle graph /aka/ pie chart
Circumference of a circle = (pi) x diameter of the circle therefore,pi = Circumference/diameter or plot a graph of circumference against diameter using many circles and the slope of the line on the graph would be equal to pi.
a collumn graph
