Answer:
Step-by-step explanation:
Triangle P is mapped onto Q so P is the initial triangle that will transformed.
We can rotate counterclockwise 90° but we cannot do it about the origin (0,0) because the red point (5, 1) will end up at ( -1, 5) .
We see that the point (5, 1) ends up at ( -2, 4) so the center of rotation is lower than the origin.
The transformation is rotation of 90° about the point (0,-1)

<u>Area of a Circle</u>
A circle is a geometric shape where all the points on its circumference are at the same distance to a fixed point called center. The radius is the distance from the center to any point of the circumference.
The relation of the length of the circumference to the radius is an irrational number called pi ().
Another interesting relation in a circle is the area it occupies in a 2D space. Being r the radius of the circle, the area is computed by the formula
The party hat has a radius of r= 3 inches. The area of the circular base is computed as follows
