What are the first 100 digits of Pi? How would I make a graph of the frequency of each digit? How would I find the mean of the first 100 digits? Then how would I creat a circle graph of the information in the bar graph?

Question

Help please.

The bar graph is simple. Count the number of times a digit occurs, and plot it as the bar.

Circle? divide the height of each bar by 100, that will be the percent frequency for that number. Divide the cirle up into ten pieces, each the size of that numbers frequency. (angleof piece equals percentfrequency*360 degrees).

Here are the first 100 digits of Pi:

3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825

To make a bar graph of the frequency of each digit, follow these steps:

1. Count the number of times each digit (0-9) appears in the first 100 digits of Pi.
2. Create a horizontal axis with the digits 0-9.
3. Create a vertical axis with counts (possibly in increments of 1 or 2).
4. For each digit, draw a bar proportional to its count above the corresponding number on the horizontal axis.

To find the mean of the first 100 digits, do the following:

1. Sum all the digits within the first 100 digits of Pi.
2. Divide the total by the number of digits (in this case, 100).

Note: Exclude the initial digit 3 and the decimal point while calculating the sum.

To create a circle graph (pie chart) of the information in the bar graph:

1. Calculate the percentage frequency of each digit by dividing its count by the total number of digits (100 in this case) and multiplying by 100.
2. Draw a circle and divide it into 10 sections, with the angle size of each section corresponding to the percentage frequency for each digit (as mentioned in the answer above: angle of the piece = percent frequency * 360 degrees).
3. Label each section with the corresponding digit and its percentage frequency.

Now you have a bar graph, mean of the digits, and a circle graph representing the information of the first 100 digits of Pi.
