A circle that is ten feet in diameter has a circumference of (approximately) 31.4 feet.
The circumference of a circle if the diameter is 10 feet long is: Pi x 10 (about 31.416).
If ten inches is the diameter, the circumference is 31.4159 inches.
1.9 and the diameter is ten
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.
Circumference = pi * diameter = 3.14159 * 11.6 = 36.44 Rounded to the nearest ten, that is 40 units.
Because C=Ï€.d the answer is 3,183 in.
10 x pi ie 3550/113 = 31.416"
25 pi sq ft
You would need enough fabric to make a circular cloth ten feet in diameter (assuming you mean the tabletop is a circle eight feet in diameter - you aren't exactly clear on that - whether the tabletop is 8 feet in diameter or 8 feet in circumference).
Five feet (r = d/2).
5 because the radius is half of the diameter
