Answer:

14 in

Step-by-step explanation:

The circumference is given as 28x, but it should be [tex]28\pi[/tex]

Now, the formula for circumference of a circle is C = 2πr

Where C is the circumference (given as 28π) and r is the radius

Lets plug it in and find r:

[tex]C=2\pi r\\28\pi = 2\pi r\\r=\frac{28\pi}{2\pi}\\r=14[/tex]

THus, radius is 14 inches
