Find the first semicircle area
Area semicircle can be determined by dividing the full area of circle by 2.
The first semicircle radius is 5 cm
semicircle area = 1/2 circle area
semicircle area = 1/2 × π × r²
semicircle area = 1/2 × 3.14 × 5²
semicircle area = 1/2 × 3.14 × 25
semicircle area = 39.25 cm²

Find the second semicircle area
Because the dimension of the second semicircle is congruent to the first semicircle, they have similar area measurement, 39.25 cm².

Find the quarter circle area
The area of quarter circle can be determined by dividing the full area of a circle by 4.
q circle = 1/4 × area of circle
q circle = 1/4 × π × r²
q circle = 1/4 × 3.14 × 10²
q circle = 1/4 × 314
q circle = 78.5 cm²

To find the entire area, add the area above together
area = first semicircle + second semicircle + q circle
area = 39.25 + 39.25 + 78.5
area = 157

The area of shaded region is 157 cm²

9 5/9 - 6 5/6 simplify if necessary im in fifth grade so i dont do negative numerals yet. ...?
adell [148]
It is not as tough a problem as it seems to you. You can easily grasp the problem, once it is done,

9 5/9 - 6 5/6 = 86/9 - 41/6
                    = (172 - 123)/18
                    = 49/18
                    = 2 13/18

I hope that the simplification process is simple enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.

What direction will this object accelerate? Please give me an explanation as well I will be marking brainiest (NO LINKS)
serg [7]

Answer:

The object will accelerate upwards.

Step-by-step explanation:

If you have two opposite forces acting on an object, the stronger one will be expressed. In this case, since 300N is upwards and 200N is downwards, 100N of upward force will be expressed.

We probably couldn't go to all the stars because they're too far away. It would take a long time to get there.
Dvinal [7]

Answer:

The correct answer is B. Contain generalizations and contractions.

Step-by-step explanation:

A generalization occurs when a specific idea is applied to a general category, in simple terms it occurs if a person states something always occur because this person saw it once. In this case, generalization occurs as this person affirms all stars are too far away and thus it will take a long time to get to those stars, however not all stars are as far away as this person believes and this does not mean it will take a long time to get there as new technology can be created, thus, this statement is not true and need revision. On the other hand, contractions refers to the process of shortening words by putting them together, this can be seen in "couldn't" ( could + not) and  "they're" (they + are), contradictions are not correct as they should not be used in formal language and be avoided, thus, contradictions also need to be revised.
