Hello!
This is strange. It seems to give you the answer.
I am assuming your teacher would just like you to identify what a radius is.
All the same, I'll let you know the equation for finding a radius.
r= d × 2 (D is equal to diameter, and r to radius)
If you were given the diameter,, you would simply multiply it by 2 to get your radius.
The correct answer to your question is:
7 inches.
