Help pls!!! And thank you

Answer:
10 ft
Step-by-step explanation:
In all circles, there is diameter and a radius
A diameter is the line going from one side of the circle to their other through the center. It is twise the size of the radius
A radius is half of the diameter, it is a line going from the center to any point on the edge of the circle
In this case, we have the radius shown to us
Since we know the radius, it is very easy to find out the length of the diameter
The diameter is twice the radius, equation D= R x 2
So we just multiply 5 by 2
This gets us to 10 so that is our final answer!
I hope this helps, and please award brainliest if possible!
Have a great day!
