the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
diameter times 3.14159
circumference = diameter x pi where pi is a constant = 3.14159 circumference = 12 x 3.14159 = 37.69908 feetPlease see the article on finding the circumference of a circle:How_do_you_find_the_circumference_of_a_circle
PI times the DIAMETER
3.14 to the 2 power
The unit for a circumference is the same as the unit for length (or radius or diameter).
Divide the circumference by 2*pi because 2*pi*radius = circumference
Circumference of a circle = (pi) x (diameter)
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
4*pi*r2. because surface area is equal to circumference of circle.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
Circumference = 2 x pi x radius
The value of Pi
