15.9

Answer 2

Answer: 15.9 centimeters.

Step-by-step explanation:

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

$C=2\pi r$

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:

$50cm=2(3.14)r\\\\r=\frac{50cm}{6.28}\\\\r=7.96cm$

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:

$D=2r\\\\D=2(7.96cm)\\\\D=15.9cm$
