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 [tex]C=2\pi r[/tex]
Where
C is the circumference
r is the radius
Plugging in 16π into C and solving for r gives us the radius. Shown below:
[tex]C=2\pi r\\16\pi = 2\pi r\\r=\frac{16\pi}{2\pi}\\r=8[/tex]
the radius is 8
