To create an area that is 1.5 m^2 in size, you will need to make use of a total of 27 triangles.
<h3>How many triangles are needed to compose a region that is 1.5 square meters?</h3>
A square that has a size of one square meter is divided into nine smaller squares that are similar to each other. Each of the little squares is divided into two triangles that are similar to one another.
There are nine smaller squares contained inside one square meter, since 1 square meter may be broken down into nine identical smaller squares. Each of the little squares is divided into two triangles that are similar to one another. 9 smaller squares may be broken down into the following:
9*2=18 (shows identical triangles)
Hence, 1 square meter is decomposed into 18 identical triangles.
We need to find the number of triangles needed to compose a region that is square meters
where
m^2 = 1.5 m^2
Where
1 m^2 = 18 identical triangles.
1.5 m^2 = 1.5 * 18
1.5 m^2 = 27 identical triangles.
In conclusion, To create an area that is 1.5 m^2 in size, you will need to make use of a total of 27 triangles.

The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³
<h3>Volume of composite object</h3>
The sphere is a a solid 3-dimensional object. THe formula for calculating its volume is expressed as:
V = 4/3πr³
where:
r is the radius of the sphere
<u>For the outer sphere:</u>
V = 4/3π(20)³
<u>For the inner sphere:</u>
V = 4/3π(4)³
The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³

Second option.
Functions are typically graphs that do not have a repeating y.
By going through each one of the given choices, you can deduce that only the second option has no repeated y values.
Hope this helps!
I think the answer is is 5-10 because I use to do this before and all ways did it right.
