Best Answer:<span> </span><span>So first we need both areas, then we can relate them, and then divide the circle by the square:
A(circle) = πr^2
A(square) = L*W or (2r)*(2r) which is (2r)^2
For the square, we know this is true because because the radius is half the diameter, so if we multiply the radius by 2, we get the length of one side of the square. We also know that the lengths of both sides of the square are the same by definition of a square.
Ratio: (πr^2)/(4r^2) = π/4</span>

I usually just multiply the number by the percentage and it works out just fine :)
Answer: For the value of w=4, 
is a true statement.
Step-by-step explanation:
Since, the given expression,
= 
= 
= 
( by subtraction property of equality)
⇒ 
( By division property of equality)
⇒ w=4 ( By multiplication property of equality)
