The area of a circle is determined by multiplying the square of its radius by the constant pi. The radius is defined as one half the diameter. The value of pi is 3.14. So, 3.14 * 62 = 113.1 square feet. Since a bag of topsoil covers three square feet, you will need 38 bags, because 113.1 square feet divided by three square feet per bag yields 37.7 bags.
38
If you want to find the size of your circular garden you will need a scientific calculator to do some sums. here are the methods.The area of the garden is equal to Pi times the square of the radius. To find the radius, measure from the edge of the circle to it's middle point, cutting a slice of cake.The circumference of the garden (the length of it's outer edge) is equal to Pi times it's diameter. To find the diameter, measure the length from one side to the other, cutting through the center point.
pi x diameter = 3.14 x 10 = 31.4 feet
The perimeter is the sum of the sides if oblong and the circumference if circular. If the garden is oblong in shape then the perimeter is 2 x length + 2 x width.
The circumference of the garden equals Pi (3.142) times diameter, therefore the circumference is 3.142 multiplied by 77 yards, which is equal to 241.93 yards. The answer is 3.142 X 77 = 241.93 yards.
The area is 63.6 square metres, approx.
200.96 square feet.
The diameter is twice the length of radius, so it is 28 feet.
C=pi*diameter 113.04=3.141592654*d d=113.04/3.141592654 d=35.98
This will depend on what is under the topsoil.
Circumference = pi x diameter = 3.1415 x 12 = 37.698 feet
To create a new garden he would have to get some topsoil and put it there.

You will require 61 bricks.
The biggest diameter that would fit is 20 ft.
Because it's awesome goddamnit!
http://www.rubberecycle.com/ I heard is selling $14 lb bags of Rubber Mulch! In all colors and the black ones are only $12! Each bag covers 13 square feet and 2 inches thick!
I have heard that the best topsoil is any composted material that consists of important nutrients or potting soil mixes. Here is a link to a video all about topsoil. http://www.ehow.com/video_4754112_best-types-topsoil.html
