If the original number is ab it has a value of
10a+b when it is reversed it will have a value of 10b-a
10b+a-10a-b is the differences which is equal to
9b-9a
So the numbers must be divisible by 9

Hey there!
In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14).
First, we need to undo the area and find the radius.
78.5/3.14=25
√25=5
Since the diameter is twice the radius, we multiply or radius by two.
5*2=10
Therefore, our edge is 10 feet from one edge to the other.
I hope this helps!
