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.

14 pi inches = a whisker under 44 inches

In which computer language?
Because it was found that there was a direct relationship between the radii (or diameters) of circles and their circumferences.
To find the ratio of the circumferences of two circles with areas 6π m² and 150π m², we first calculate their radii. The radius ( r ) of a circle can be found using the formula for area ( A = \pi r^2 ). For the first circle, ( A = 6\pi ) gives ( r_1 = \sqrt{6} ), and for the second circle, ( A = 150\pi ) gives ( r_2 = \sqrt{150} ). The circumferences are ( C_1 = 2\pi r_1 = 2\pi \sqrt{6} ) and ( C_2 = 2\pi r_2 = 2\pi \sqrt{150} ). Thus, the ratio of the circumferences is ( \frac{C_1}{C_2} = \frac{\sqrt{6}}{\sqrt{150}} = \frac{\sqrt{6}}{5\sqrt{6}} = \frac{1}{5} ).
First you times 3.14 by the diameter and there you go
