Multiply the diameter by 3.14 (pi).
Circumference of circle: 5.5 times pi
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
Divide the diameter by 2. (The radius is 1/2 of the diameter.)
A circle with a radius of 5.
The diameter of a circle is twice its radius.
16 cm
Using 3.14 as Pi the area of circle is: 0
Multiply the diameter by 3.14 (pi).
Circumference of circle: 5.5 times pi
yes the radius is half the diameter. It goes from the edge of the circle to the centre.
since the equation to get circumference is diamiter X pi, and the diamiter is 2x the radius, yes it would double the C of the circle ie before radius is 2, so diamiter is 4 4 X Pi 12.57... radius is 4 so the diamiter is 8 8 X pi = 25.13... that would double it.
Using 3.14 as Pi the area of circle is: 132.665
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
Divide the diameter by 2. (The radius is 1/2 of the diameter.)
well you can divide the circumference by pi (3.14) and it will always give you the diameter or you could measure it.
