Circle q has a ciecumference of approximately 50 centimeters. what is the approximate length of diameter d, use 3.14 for pie. round to the nearest tenth of a centimeter

15.9 centimeters.

Step-by-step explanation:

The formula for calculate the circumference of a circle is this one:

Where "C" is the circumference of the circle and "r" is the radius.

We know that:

[tex[C=50cm\\\pi=3.14[/tex]

Then, substituting these values into the formula and solving for "r", we get:

Since the diameter of a circle is twice the radius, we can multiply the radius by 2 to get the diameter of this circle. Then, rounded to the nearest tenth of a centimeters, this is:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
