The length of the border is approximately 4 feet.
Step-by-step explanation:
Since the garden has a circular border we can apply the formula for the circle's length, which is shown below:

Where the radius is half the diameter. The diameter is the distance between two points in the circle going through the center, therefore for this garden the diameter is 1.2 feet and the radius is 0.6 feet. Applying this to the formula gives us:

The length of the border is approximately 4 feet.
Answer:
move the decimal point in 4.082 4 places to the left
Step-by-step explanation:
i hope this helps :)
If the diameter is 30 ft then the area of the circle is 706.5 you can approximate it if you want and you will have 707.
