Question

The formula for the circumference of a circle C equals two pi R where are is the radius and see is the circumference equation solve for our is our equals C over two pi find the radius of the circle that has a circumference of 16 pi

Answer 1

Answer:

8

Step-by-step explanation:

The question is basically "Find the radius of the circle that has a circumference of 16π"

The formula for circumference of a circle is given as  $C=2\pi r$

Where

C is the circumference

r is the radius

Plugging in 16π into C and solving for r gives us the radius. Shown below:

$C=2\pi r\\16\pi = 2\pi r\\r=\frac{16\pi}{2\pi}\\r=8$

the radius is 8
