Find the area of the shaded region. round answers to the nearest tenth. assume all inscribed polygons are regular. 29.3 units2
FromTheMoon [43]
The picture in the attached figure

we know that
the area of the shaded region is equal to
(2/3)*[area of the circle - the area of the triangle]  

step 1
Find the area of a circle Ac
Ac = π r²
Ac = π (6)²
Ac = 113.10 units²

step 2
find the area of the triangle At
The triangle is an equilateral triangle with angles on each corner equal to 60 degrees. Meanwhile,
the 3 angles at the center is 120 degrees each since a circle is 360 degree.
 We know that the radius (line from centerpoint to corner) is equivalent to 6.
Using the cosine law,
we can calculate for the length of one side.
s² = 6^ + 6² – 2 (6) (6) cos 120
s² = 108
s = 10.4 units
Since this is an equilateral triangle, therefore, all sides are equal.
The area for this is:
At = (sqrt3 / 4) * s²
At = 46.77 units²

step 3
the area of the shaded region=(2/3)*[area of the circle - the area of the triangle]  
the area of the shaded region=(2/3)*[113.10-46.77]------> 44.22 units²

therefore

the answer is
the area of the shaded region is 44.22 units²

Find each sum.
Greeley [361]

Answer:

Sum is - 5n² -8n + 4.

Step-by-step explanation:

Given : (3n² – 5n + 6) + (–8n²– 3n – 2) .

To find : Sum .

Solution : We have (3n² – 5n + 6) + (–8n²– 3n – 2) .

Combine like terms :

(3n² - 8n²– 5n - 3n + 6 - 2).

- 5n² -8n + 4.

Therefore, Sum is - 5n² -8n + 4.

Can someone please answer A and B please?
marta [7]

2 bags

7 apples


A) Instead of a lets say:

a = 1, 2 , 3

If a =1  then, (you already know there are 2 bags) you have 1 apple in each bag, making total of 2 apples

If a =2 then you are having 2 apples in each bag making total of 4 apples

If a =3, 3 apples in each bag, making total of 6 apples

Conclusion:

2 * 1 = 2

2 * 2 = 4

2 * 3 = 6

See the difference & pattern here

Now lets do with a

2 * a = 2a


B) If a = 6

then,  2*6 = 12

lets continue from a =3

2*4=8

2*5=10

2*6=12

See the pattern again


Tip: Drawing making problem understand better.
