Answer:
Square root property
Step-by-step explanation:
X = width

Answer:
d ≈ 10.5
Step-by-step explanation:
The formula for the diagonal of a retangular prism (cuboid) is

1.) Plug in all the values for l, w, and h

2.) simplify by squaring the terms inside the square root
5 * 5 = 25
6 * 6 = 36
7 * 7 = 49

3.) Add the terms

4.) Simplify

5.) Round to one decimal place
d ≈ 10.5
The radius is half of the diameter.
9/2=4.5
The radius is 4.5 feet.
Hope this helps!
