Answer:
2.3, 2.8, 3.01, 3.017, 3.10, 4.125, 4.2
Or
Step-by-step explanation:
The given numbers are
To arrange them we will covert the fractions into decimals first.
Let's understand which number is greater among 2.3 and 2.8.
Here 2 is common in both the numbers but after decimal one number has 2 and other 8.
So number having greater number after decimal will be greater than the other one.
Therefore, out of 2.3 and 2.8, 2.8 will be greater.
Now we will arrange all the numbers from least to greatest.
2.3, 2.8, 3.01, 3.017, 3.10, 4.125, 4.2

Answer:
Step-by-step explanation:
The smallest side of a triangle is formed by the smallest angle in the triangle.
To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, , where
,
, and
are the three sides of the triangle and
is the angle opposite to
.
Let be the side opposite to the 20 degree angle.
Assign variables:
Substituting these variables, we get:
Therefore, the shortest side of this triangle is 3.5.
Given:
A circle of radius r inscribed in a square.
To find:
The expression for the area of the shaded region.
Solution:
Area of a circle is:
Where, r is the radius of the circle.
Area of a square is:
Where, a is the side of the square.
A circle of radius r inscribed in a square. So, diameter of the circle is equal to the side of the square.
So, the area of the square is:
Now, the area of the shaded region is the difference between the area of the square and the area of the circle.
Therefore, the correct option is (a).
