Step-by-step explanation:</h3>
In this question, we're trying to find the radius of the circle.
In this case, we would use the formula:

"A" would represent the area, so you would plug in 73.48 in "A."
Your equation should look like this:

Now, you will solve:

When you're done solving, you should get 4.836
This means that the radius is about 4.836 meters.

Answer:
1. (x,y)→(y,-x)
2. (x,y)→(-y,x)
3. (x,y)→(-x,-y)
Step-by-step explanation:
1. Rotation 90° clockwise (or 270° counterclockwise) about the origin changes x into y and y into -x, so it has the rule
(x,y)→(y,-x)
2. Rotation 90° counterclockwise (or 270° clockwise) about the origin changes x into -y and y into x, so it has the rule
(x,y)→(-y,x)
3. Rotation 180° clockwise about the origin changes x into y and y into -x, so it has the rule
(x,y)→(-x,-y)
Here you can apply rotation by 90° clockwise twice, so
(x,y)→(-y,x)→(-x,-y)
