I have about 6 areas that I've measured only in Feet and Inches. I need to find out how much yards of gravel I need in order to get the spaces filled in properly.

3 of the areas contain circles.

Now here is what I've done for the squared areas. I added the length and width and divided by three feet or one yard.

For the Circle Area I divided the Width by 2 in order to determine what the radius was. Then I squared the radius by multiplying the radius by itself one time. Then I multiply by 3.14 which is PI. Then I divide by three feet or one yard. It' giving me a number of yardage that might be the right amount, but I'm not 100% sure.

I started out below with the first two, but not sure if this is correct

Front Side Yard 31'L X 31'W=20.6 Yards

Left part of Wall Where Trailer is Front 27'L X 18'9''W= 15.3 Yards

Trailer Area 24'L X 12'W=

Tennis Area to Front not including Trailer Area 65'L X 53'W=

Whole Area Tennis To Front 65'L X 65'W=

Back by Sliding Glass Door 12'6''L X 3'4''W=

First Circle 16'9''L X 10'1''W=

Second Circle 16'5''L X 12'11''W=

Third Circle 11'3''L X 12'W=

Here is the Design I made in Paint also

In order to properly figure, you need to know the depth also.

Just for an example 1 cubic yard of material will fill an area 10 feet by 10 feet or 100 square feet 3 inches deep.

I was able to self teach myself earlier on this subject. Length X Width X Depth / 27 for approximate Yardage.
I even made an educational post for my viewers to see on my blog every time I advertise my services. Click here (http://tucsonqualitylandscaping.blogspot.com/2010/12/affordable-gravel-spreading-in-5-easy.html) for immediate navigation to the statistics!

Try experimenting with the mulch calculator (http://www.gopherforum.com/showthread.php?p=43299#post43299) here. You can use it to calculate the amount of mulch of potentially gravel you would need for different shapes and then combine them all together to get a total.
