If it is then find out where to get it and then get it!
You will need 1500 cubic feet.
The area of a 10 foot circle is: 78.54 square units.
An area 10 foot x 10 foot is 100 square feet. 100 cubic feet of sand would cover it with a one foot deep layer of sand. If the sand needs to be 6 inches deep, then 50 cubic feet are be needed, or 25 cubic feet if the sand is to be 3 inches thick.

130 square feet
A linear foot is distance. A square foot is area. One square foot is the area of some square tiles used on floors. Ten square feet is 1 foot x 10 feet or 2 feet x 5 feet. Don't confuse this with a 10 foot square which is 10 feet by 10 feet which equals 100 square feet.
For simplicity sake, let's assume we have a 10 foot x 10 foot room with an 8 foot ceiling. The floor area is 10 multiplied by 10 to get 100 square feet. To get the volume multiply that by 8 and get 800 cubic feet.
160 square feet. You times length by width.
Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
78.5 square feet.
