Answer:

  see attached

Step-by-step explanation:

Rotation 270° counterclockwise is equivalent to rotation 90° clockwise. The transformation of coordinates is ...

  (x, y) ⇒ (y, -x) . . . . . . . rotation 270° CCW

This means the points are moved to ...

  A(-2, 1) ⇒ A'(1, 2)

  B( 1, 2) ⇒ B'(2, -1)

  C(-2, 4) ⇒ C'(4, 2)

The rotated triangle is shown in the attachment. You may notice that A' and B are the same point.

A circle with radius 3 has a sector with a central angle of 1/9 pi radians
marissa [1.9K]

Complete question:

A circle with radius 3 has a sector with a central angle of 1/9 pi radians

what is the area of the sector?

Answer:

The area of the sector = \frac{\pi}{2} square units

Step-by-step explanation:

To find the area of the sector of a circle, let's use the formula:

A = \frac{1}{2} r^2 \theta

Where, A = area

r = radius = 3

\theta = \frac{1}{9}\pi

Substituting values in the formula, we have:

A = \frac{1}{2}*3^2* \frac{1}{9}\pi

A = \frac{1}{2}*9* \frac{1}{9}\pi

A = 4.5 * \frac{1}{9}\pi

A = \frac{\pi}{2}

The area of the sector = \frac{\pi}{2} square units
