Sam rotated parallelogram ABCD 90° clockwise around the origin. If angle A is 130° and angle B is 50°, what is the degree measur
irakobra [83]

<u>Answer-</u>

The measurement of angle A' will be 130° .

<u>Solution-</u>

Transformations like - rotations, reflections, and translations are isometric.  That means that these transformations do not change the size of the figure.  If the size and shape of the figure is not changed, then the figures are congruent.

It doesn't matter the order or how much degree of rotation has taken place, the final image will be congruent to the original image.

So, even after the rotation of 90° clockwise around the origin, the measurement of angle A will be 130° and so do all the rest of the angles.

A circular plate has circumference 28.3 inches. What is the area of this​ plate? Use 3.14 for pi.
natima [27]

Answer:

A =63.76512739 in^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi * r

28.3 = 2* 3.14 *r

28.3 = 6.28r

Divide each side by 6.28

28.3/6.28 = 6.28r/ 6.28

4.506369427 =r

Now we need to find the area

A = pi r^2

A = 3.14 (4.506369427)^2

A =63.76512739 in^2

Dawson is covering a large cylinder with brown paper. He'll need to find the volume of the cylinder in order to determine how mu
jok3333 [9.3K]
False.

The volume of a cylinder is how much space it takes up INSIDE. You would use volume to measure how much you can put something inside (like water)

Surface area measures the OUTSIDE of a shape. In this case, you'd use surface area to determine how much paper he needs.
