Calculating the Circumference of a Circle
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle.
How to find the circumference of a circle:

The circumference of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56
If you know the radius, the diameter is twice as large

so take 3.14 x 20 = 62.8
62.8 divided by 2 = 31.4

so you only need 31.4 feet of rod to get 10 feet tall .

hope i figgured that right good luck
