Your Data:

Get your data sheet from the "Plant Survey" activity.
You will need it to complete this part of the investigation.

Here is how you do it:
For each species of tree, follow the steps below.
Do the calculation asked for in the step. 
As you get each answer, write the answer in the table.

    step 1.  Add up all of the circumferences for the trees of a particular species.
                 Write this number in the table.

    step 2.  Divide this number by the number of trees of that species.
            This is the average circumference
                 
Write this number in the table.
    step
3.  Divide this number by 3.14

            This is the average diameter
                  Write this number in the table.
    step 4.  Divide the average diameter by 2

            This is the average radius
                  Write this number in the table.

    step 5.  Multiply this number times itself (square the number).
                  Write this number in the table.

    step 6.  Multiply this number by 3.14
            This is the average area of that tree
                  Write this number in the table.
    step 7.  Multiply this number by the number of trees that you found of that one species.

            This is the total area taken up be this particular species of tree.
                  Write this number in the table.

Follow this same procedure for each species of tree that you have found.
Put all of your data into the table below.

Here is how to use this data table:
Each column will be the data for one tree species.
Follow the steps above for each column.
Do the calculation for each step.
Write the answers in the boxes.
