Given that z is inversely proportional to x, then:
z α 1/x
hence;
z=k/x
where:
k is the constant of proportionality; 
when x=6, z=2
therefore;
2=k/6
hence;
k=2*6=12

Therefore:
z=12/x
the value of z when x=13 will be:
z=12/13
the answer is 12/13

The radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's dia
Liula [17]

Answer:

π = C / d

Step-by-step explanation:

The circumference of a circle is given by the general formula;

C = 2 * π * r .... or C = π d  (r = radius, d = diameter)

We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:

π = C / d

To obtain π, you need to divide the circumference by the diameter.

We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d...  it's also convenient to use the diameter.
