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

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.
14 pi inches = a whisker under 44 inches
Concentric and coincident, perhaps.
In which computer language?
Because it was found that there was a direct relationship between the radii (or diameters) of circles and their circumferences.
First you times 3.14 by the diameter and there you go
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} ).
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
