Answer:
Step-by-step explanation:
step 1
Find the area of the circle with a diameter of 9 units
we know that
The area of a circle is equal to
we have
----> the radius is half the diameter
substitute
step 2
Find the area of a square with a side length of 8 units
we know that
The area of the square is
where
b is the length side of the square
we have
substitute
step 3
Equate the areas
solve for 
When you are rounding to the nearest tenth, you only look at the number right to the tenths which in this case is 5, so you round up the 6 to a 7, which will be.

I believe that its easier to understand the multiplication of a radical than that of a polynomial.
<h3>How to illustrate the information?</h3>
In mathematics, a radical is the opposite of an exponent that is represented with a symbol '√' also known as root.
A polynomial is an expression which is composed of variables, constants and exponents, that are combined using the mathematical operations such as addition, subtraction, multiplication and division.
When multiplying radicals with the same index, multiply under the radical, and then multiply in front of the radical. An example is:
= 3✓2 × 4✓2
= 12✓4
= 12 × 2
= 24
The multiplication of a radical is easier.
