The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
area = 2pi*r2circumference = 2pi*rThe ratio of their circumferences will be 2pi*r1 /2pi*r2 = r1/r21) r2 = 6pi/2pi = 3. r1 = root(3).2) r = 150pi/2pi = 75. r2 = root(75)So the ratio of their circumferences isr1/r2 = root(3)/root(75)
Ratio of circumference is π : 4π = 1 : 4 This is the ratio of all lengths, therefore their radii are in the ratio of 1:4 also. Ratio of areas is the square of the ratio of length → ratio of their areas is 1² : 4² = 1 : 16
A diagon, is an example of a two sided shape, which is basically a secton of a sphere emcompassed by two circumferences disecting. or a plane (e.g a sheet of paper) or a strip (a simple ring shape)
You can find regulations about clothing sizes in the EN 13402 standard, and a series of physical measurements in the SIRI-dataset. Reading the standard, I see that t-shirt sizes (men), for example, are mainly based on chest circumferences. Size 'M' is suitable for chest circumferences between 94 and 102 cm. Size S is 8 cm smaller, size L is 8 cm bigger, XL is 16 cm bigger and XS is 16 cm smaller than size M. When I calculate the median and standard deviation of all the chest circumferences (adult males) I find in the SIRI-dataset, I find a median of 99.6 cm, and - surprise - a standard deviation of 8.4 cm. So, I tend to believe that clothing sizes follow, in some way, the normal distribution. Size M refers to the median size, and the intervals between the size codes have about the same value as the standard deviation. So, size S is one standard deviation smaller than size M, and XL is two standard deviations bigger than size M. If haven't checked other types of clothes and other physical sizes, so I cannot guarantee that my conclusion is correct for any type of garment.
They are circumferences
An arc
It is the planet's diameter multiplied by pi
The answers depend on what you want to "do" and what information you have.
They are its circumferences
d = 9.55 cm
Only one.
First you times 3.14 by the diameter and there you go
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
whats the circumferences of r=8
79.20 0 is the hundredth place.
They have a circumference which is 2*pi*radius or diameter*pi They have an area which is pi*radius2 They have sectors They have chords They have segments They have a total of 360 degrees around their circumferences They have arcs which is part of their circumferences They can have a tangent which is a straight line that touches it at one point
