It is called a point of concurrency
Answer:
The volume (density) of cement that will be needed to cover this hollow pipe is:
= 50,000 kg/m³
Step-by-step explanation:
Length of a cylindrical pipe = 5m
Width of the cylindrical pipe = 4m
Depth of the cylindrical pipe = 2.5m
The cubic meters of the cylindrical pipe = 5 * 4 * 2.5 = 50m³
1 cubic meter is equal to 1,000 kilogram
Therefore, the volume (density) of cement that will be needed to cover this hollow pipe is:
= 50 * 1,000
= 50,000 kg/m³
22/7 = 3.142857...
Let's see if we can beat this using a fraction with 113 as its denominator.
-------
3 x 120 = 360
-------
So, let's try out x = 360:
360/113 = 3.185.... (Too high)
How about x=350:
350/113 = 3.097... (Too low)
Let's try out x = 355:
355/113 = 3.14159292 (Calculator value)
--------
Let's now compare 22/7 and 355/113 to pi:
22/7 = 3.142857...
355/113 = 3.14159292 (Calculator value)
π = 3.141592654
-------
As we can see, 355/113 provides us with a better approximation of π. This means that x=355.
