If you are given the radius (r) or diameter (d, which is twice the length of the radius) the equation to find the circumference (C) is: C=d(pi) or C=2r(pi).
They are its circumferences
Only one.
d = 9.55 cm
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
Concentric and coincident, perhaps.
The perimeter of a circle
They are its circumferences
Only one.
d = 9.55 cm
because its used to calculate areas of circle, circumferences and so on
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
14 pi inches = a whisker under 44 inches
Concentric and coincident, perhaps.
In which computer language?
First you times 3.14 by the diameter and there you go
Because it was found that there was a direct relationship between the radii (or diameters) of circles and their circumferences.
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi
