40.8
Diameter of the circle: 24 feet
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
If the area is a circle, the radius would be 186.2 feet.
The circumference of a circle is pi x diameter, where pi equals approximately 3.14. Therefore, the inner circumference of a brick circle with an inside diameter of 10.5 feet is 32.99 feet. As a result, 33 one foot bricks would create a circle with a diameter slightly larger than 10.5 feet, without any gaps between the bricks.
40.8
26 feet plus twice the length.
A length of approx 18.85 feet.
Circumference = pi x diameter = 3.1415 x 12 = 37.698 feet
Assuming the 28 feet refers to the diameter of the circle, the answer is 1231.5 cubic feet, approx.
40.8 feet
It would be about 56.5 feet.
area of a circle is calculated using the formula a=(pi)r2 where a is the area and r is the radius of the circle. so:if the diameter(distance from one edge of the circle to the other that passes through the mid point) of your circle is 40 feet then you would need approximately 1256 square feet give or take a couple square inches.if the circumference (length around the edge of the circle) of your circle is 40 feet then the over all area is 127.38 square feet.
Diameter of the circle: 24 feet
If the circle is 8 feet in diameter, its circumference would be: 25.13 feet (diameter x Pi = circumference)
The formula for circumference is 2 x pi x radius. For a circle of 10 feet, the cirumference would be 62.8 feet. The formula for area is pi x r2. For a circle of 10 feet, the radius would be 314.16 ft.
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
