Answer:

75.4cm

Explanation:

The (C) of a circle is given by the formula:

C = 2πr where r is the radius of the circle.

Given that the radius is 12 centimeters, we can plug this value into the formula:

C = 2π×12

Calculate the circumference:

C = 24π centimeters

So, the circumference of a circle with a radius of 12 centimeters is 24π centimeters, which is approximately 75.398 centimeters.

Answer: C = 75.4 cm

Explanation:

In order to find the circumference of the circle, I am going to use the following formula:


\bigstar\quad\underline{\boxed{\sf{C=\pi d}}}

We're given the radius; if we multiply it by 2, we'll get our diameter.


\bullet diameter = 12 * 2 = 24 cm

Now, plug the values into this formula:


\twoheadrightarrow\quad\sf{C=\pi*24}


\twoheadrightarrow\quad\sf{C=75.4\;cm}
