Answer:
Step-by-step explanation:
<h2>
<em><u>First</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Sides of a square = 3 cm
Therefore, area of the square = <em>side × side</em>
= 3cm × 3cm
<h2>
<em><u>Second</u></em><em><u> </u></em><em><u>c</u></em><em><u>ase</u></em><em><u>:</u></em></h2>
Radius of the circle = 4cm
Therefore, area of the circle
<h2><em><u>Last</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>
Area of the shaded region
= <em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>circle</em><em> </em><em>-</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>square</em><em> </em>
Here's the thing, just as squaring a number "un-does" its square root, sin "un-does"
. So if you're taking the sin of its inverse, what you get back is what you started with. The sin of the inverse sin of sqrt(3)/2 is sqrt(3)/2, choice b.

There are 3 answers: Choice A, Choice D, Choice F</h3>
Explanation:
2 & 1/2 = 2.5
10 + (-2.5) can be represented by starting with 10 and then dropping by 2.5, which is what choice A is saying
or we can start with -2.5 and add on 10. This works because we can add numbers in any order, example: 2+3 = 3+2 = 5. So starting with -2.5 and adding on 10 is represented by choice D's and choice F's examples
The length of the painting is 1/4.
According to the statement
we have to find the length of the rectangular painting with the help of the given information.
So, For this purpose, we know that the
The given information is:
The area of a rectangular painting is 1/6 square yard. The width is 2/3 yard.
And we have to use the formula
Area = Length * Breadth
So, Substitute the values in it then solve
So,
Area = Length * Breadth
1/6= Length * 2/3
1/6 = 2L/3
1 = 12L/3
1 = 4L
L = 1/4.
The value of the length is 1/4.
So, The length of the painting is 1/4.
