the scale of c is the same for every instrument you can think of. But if you have what is called a transposed instrument (say in Bb or Eb (alto sax) or F (french horn) the c you play will sound different from the c on your piano. you will see that it matches the Bb on the piano so if you want to play in c concert (like the piano) you have to play the scale of d major.
The Circle of Fifths shows the relationship between the twelve tonnes of the chromatic scale. The chromatic scale is related to musical instruments.
Take the C Maj scale and sharp everything. C# D# E# F# G# A# B# C# I ii iii IV V vi vii* I
a scale
Johann Sebastian Bach 'discovered' the chromatic scale, and composed the Circle of Fifths. The Circle of Fifths starts with the key of C, which has no accidentals (flats or sharps). The fifth note of C is G, when means when you play or write these scales, you move from the key of C to the key of G - moving up a perfect fifth; hence, the term 'circle of fifths'. The key of G major has one accidental, the F sharp. The fifth note of the key of G is D, and the key of D major has TWO sharps - so you see, as you move through the circle of fifths each change increases the number of accidentals by one. For instance, the fifth note of D is A, and the key of A major has THREE accidentals. That is pretty much why the key of G major has an accidental, which in the case of that scale, happens to be F sharp.
Diatonic key signatures result from the diatonic scales. There are 15 diatonic scales and each of them have a key signature which corresponds to each scale. There is a circle of fifths which shows the system on how to come across each and every diatonic key signature and scale.
it is an instrument for measuring a person
Yes they are. In a 2-dimensional plane, a circle is completely defined by the location of its centre and its radius. The first of these is irrelevant for similarity. The second, its radius is also the circle's only scale factor. And since similarity permits changes in the scale, a circle is not changed by altering its scale factor. Consequently all circles are similar.
A scale ie required to measure the area of a circle. We need to measure the radius of that Circle and then we can put this radius valve in below mwntioned formula & can calculate the area. A=3.14*r*r where r is radius in Cm. A is are in cm square. Hemant gautam +919099921329

That depends on the instrument.
