Answer: 80

Step-by-step explanation:

First, find the area of the square by doing 12 x 12. (Which = 144)

Then, find the area of the circle. This is found by using the formula of 1/4 • π • 9 squared.

This should get you 63.62, or 64 when rounded up.

You then subtract 64 from 144 and get 80 for your answer.

The correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The formula utilised to find the distance between two points is;-

X = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.

AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Therefore the correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .
