The mass of the cylindrical clay pipe is 16.54 kg if the 2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.
<h3>What is density?</h3>It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol ρ The density is measured in kilograms per cubic meter.
We have:
2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.
The volume of the pipe:
= Volume of the cylinder(D = 15 cm)—Volume of the cylinder (D = 12 cm)
Because 2 meters = 200 cm
= 35342.91 - 22619.46
= 12723.45 cubic cm
Density = mass/volume
1.3 = mass/12723.45
mass = 16540.48 g ≈ 16.54 kg
Thus, the mass of the cylindrical clay pipe is 16.54 kg if the 2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.

Answer:
Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:
Answer:
a). We want to know how much each point was worth.
b).
c). Each problem worth 3 points.
Step-by-step explanation:
a). We want to know how much each problem was worth. Because we have the total points of the test, and how much was the bonus. But we still don't know the worth of each problem.
b). We know that the total points of the test were 41, and the bonus 5 points. There were 12 problems on the test and we are going to use "x" for the unknown part (how many points each problem was worth).
The equation is :
Why 12x? Because if you multiply the twelve problems of the test with the worth of each one and then add the 5 points of the bonus you will obtain the total points of the test (41).
c). Now we have to solve the equation, this means that we have to clear "x":
Subtract 5 from both sides.
Finally divide in 12 both sides of the equation:
Then each problem worth 3 points.
