Answer:

1) 45 degrees

2) 75 degrees

3) 37 degrees

4) 43 degrees

5) 137 degrees

Step-by-step explanation:

1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees

2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75

3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37

4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43

5) 180 - Angle 4 = 180 - 43 = 137

The area of the shaded part of the figure below can be determined in different ways. Use

lesantik [10]

The figure can be decomposed into four rectangles of the figure can be decomposed into four trapezoids with a height of 3 in. and a base of 2 in. and 5 in. The area of the shaded region is 21 square in.

<h3>What is a rectangle?</h3>

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The area of the shaded part of the figure below can be determined in different ways.

Then the figure can be decomposed into four rectangles of the figure can be decomposed into four trapezoids with a height of 3 in. and a base of 2 in. and 5 in.

Then the area of the shaded region will be

$\rm Shaded \ area = 5^2 - 2^2\\\\Shaded \ area = 25 - 4\\\\Shaded \ area = 21$

More about the rectangle link is given below.

Answer:

Purple Cylinder

Step-by-step explanation:

You are given the equation for the volume of a cylinder, which is: $r^2h\pi$ , where r is the radius of the cylinder and h is the height.

We are given both the height and radius of each cylinder in the question, therefore we can work out the volume of each of them.

Purple Cylinder:

Radius given = 2

Height given = 2

$V=(2)^2(2)\pi =(4)(2)\pi =8\pi$ , so the volume of the purple cylinder is $8\pi$ .

Green Cylinder:

Radius given = 1

Height given = 6

$V=(1)^2(6)\pi =(1)(6)\pi =6\pi$ , so the volume of the green cylinder is $6\pi$ .

Now let's compare the volumes: $8\pi >6\pi$ . $8\pi$ is larger than $6\pi$ so the volume of the purple cylinder is greater than the volume of the green cylinder.
