432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
There 12 inches to a foot, so 120 tenths of an inch to a foot.
A 12-inch circle has an area of about 113.1 square inches.
The circumference of a 10-inch diameter circle is: 31.4 inches.
In one inch there are hundred 100ths of a inch Since there are 12 inches in a foot, there will be 12 x 100 = 1200 hundredths of an inch in a foot

To calculate the number of 12-inch bricks needed for a four-foot circle, first convert the diameter of the circle to inches: 4 feet is 48 inches. The circumference of the circle is calculated using the formula (C = \pi \times d), which gives approximately (C = 3.14 \times 48 \approx 150.8) inches. Since each brick is 12 inches long, divide the circumference by the length of one brick: (150.8 , \text{inches} / 12 , \text{inches/brick} \approx 12.57). Therefore, you would need about 13 bricks to complete the circle.
this depends on the size of the bricks. Assuming 4x9 inch bricks then 3.14 x (15/2)2 x 1212 = 25434 sq inches 1 brick is 4 x 9 = 36 sq in. 25434 / 36 = 706.5 bricks but there would be some waste from cutting the bricks to make a circle.
About 240 three inch by eight inch bricks would be need for create a ten foot by four foot patio. It would be preferable to purchase another 24 or 10 percent more for wastage.

6 inches is half a foot so it takes four 6 by 6 inch bricks to make one square foot. 348 x 4 = 1392. So you'll need 1392 bricks.
How many cubic yards in an 12 foot diameter circle with a 4 inch thickness?
432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
There is no sensible answer to this question. The use of the term "a 6 foot circle" is suggestive of the area of a 6 foot circle - although whether it is 6 foot radius or 6 foot diameter is unspecified. If it is the area of the circle, there are no inches in it since an inch is a measure of length.
A 12 x 12 inch brick is 1 square foot. A 20 x 20 (foot) patio is 400 square feet, so you would need 400 bricks.. this assumes you are butting the bricks fairly tight, not leaving large seperations between them, etc...
you would need 12...
Circumference of a circle = 2*pi*radius or pi*diameter
