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

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.
you would need 12...
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...
Circumference of a circle = 2*pi*radius or pi*diameter
The lineal inch of a 90-degree circle, also known as the circumference, can be calculated using the formula: Circumference = pi * diameter. In this case, the lineal inch will be equal to pi times the diameter of the circle.
