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.
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
The circumference of a 10-inch diameter circle is: 31.4 inches.

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.
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.
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.
