If you have the circumference of a circle, how do you get the diameter and the rayon

C divided by pie = diameter

How would you make a pie chart?

First, you would figure out the total of whatever so say it was 50 then you would get all the information so all the numbers equally up to 50 you would take those numbers change into a fraction that multiply that by two which will equal usually 100 then change that into a decimal then a percentage then to get the degree, you would have to multiply the decimal by 360 and that’s your answer to the degree and now you can use all that information and build a pie chart
