A stem and leaf plot is a table where each of the data is divided into two parts. The stem, that is the first digit and the leaf is the last digits. Let's say that we have the following set of data.
If we want to make a stem and leaf plot of that data, we first write a column where we place the first digit of each number without repetition, like this:
These are the stems. Now the leaves are the last digit of each number put in order next to the corresponding first digit, like this:
To solve this we are going to use the formula for the area of a circle:
where
is the area of the circle
is the diameter of the circle
We know from our problem that the area of our circle is 10 inches long, so
. Lets replace that value in our formula to find
:
We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.
