The smallest circular piece of lace to cover the entire top of the table is 226.2 inches².

Area of circle

Length of each side of square = 12 inches

The diameter of the circle will be the length of the diagonal of the square from the given figure.

[tex]d=\sqrt{12^2+12^2}\\\Rightarrow d=12\sqrt{2}\ \text{in}[/tex]

Area of a circle is given by

[tex]A=\pi\dfrac{d^2}{4}\\\Rightarrow A=\pi \dfrac{(12\sqrt{2})^2}{4}\\\Rightarrow A=226.194\approx 226.2\ \text{in}^2[/tex]

Answer:

z = 5

Step-by-step explanation:

[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]

It can be also written as -
