Answer:
The scaling factor is 4.
Step-by-step explanation:
To find the scaling factor from A to B, we must know that these are similar triangles. Since this is not stated in the problem, we will assume these are similar triangles.
Similar triangles simply have the same scaling ratio, allowing for any size triangle to be created with the same relative dimensions. With this in mind, let's check to see the multiple of each side by simply taking the sides of the triangle B divided by the sides of triangle A.
40 / 10 = 4
44 / 11 = 4
72 / 18 = 4
Notice how each of the sides from triangle B to triangle A has the same multiple, 4. This tells us that the scale from A to B is 4.
Hence, the scaling factor is 4.
Cheers.

An equation that represents the value of the circumference, C, of a circle with a diameter of 48 feet is C=2π×24.
What is the circumference?
The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its Centre. A meridian is any great circle passing through a point designated a pole.
Given that, a circle with a diameter of 48 feet.
Here, radius = Diameter/2
Radius = 48/2 = 24 feet
We know that, the circumference of a circle is 2πr.
Now,
C=2π×24
C=2×3.14×24
C=150.72 feet
Therefore, the circumference of a circle is 150.72 feet.

The volume is (area of cross-section) x (length) .
-- The cross-section is a triangle. The area of a triangle is
Area = (1/2) (base) (height) .
In this one, the base is 9/4 m and the height is 3-1/3 m .
Area = (1/2) (9/4 m) (3-1/3 m)
Area = (1/2) (9/4) (10/3)
Area = 90/24 m² .
-- Volume = (area of cross-section) x (length)
Volume = (90/24 m²) x (7-1/3 m)
Volume = (90/24) x (22/3) m³
Volume = (1,980 / 72) m³
Volume = 27.5 m³
