A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies
C - 262 Hz
E - 330 Hz
G-392 Hz
Determine the ratio of the frequency of G to E. Express the answer in a simple integer ratio. (Due to rounding the
ratio will be approximate.)
a. 5 to 4
b. 3 to 2
6 to 5
d. 9 to 8
C.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
