What is the circumference of a circle 3ft
Divide the diameter by 2.
diameter times pi(3.14159) equals cicumference
Well, I always use this formula: pi x r2
Cicumference = π*d = 56.55 units
What is the circumference of a circle 3ft
circumference of a circle = pi*diameter or 2*pi*radius cicumference = 62.83185307 or 63 feet to the nearest foot
12pi or about 37.699
It will measure a fraction of the circle's cicumference
Divide the diameter by 2.
diameter times pi(3.14159) equals cicumference
Diameter Diameter radius
The radius of a circle is the distance from the center of the circle to any point on its circumference. In this case, if the circle has a diameter of 20 feet, the radius would be half of that, which is 10 feet. So, the radius of a 20 ft circle is 10 feet.
Well, I always use this formula: pi x r2
Cicumference = π*d = 56.55 units
diameter. a radius doesn't even run through a circle. a circumference is the line that surrounds the circle.
pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
