20 is the answer to your question use pythag theorem
Hey I’ve done some working out, check out the image, I hope it’s right
The Bible, a book that is considered the perfect word of a perfect god tells us what the value of Pi is. Let's see verse 1 Kings 7:23
He also melted a sea of ten cubits from one side to the other, perfectly round; Its height was five cubits, and a cord of thirty cubits encircled it.
These are a list of specifications for the great temple of King Solomon, built about 950 BCE, and his interest here is that it gives a value of π = 3. If we divide 30 cubits between 10 cubits (which are the measures mentioned in written radical) gives us exactly 3.
We know that the length of the circumference is calculated l = 2 · π · r; Since 2 · r is the diameter, it can also be said that
circumference = diameter × π
If we go back to what the Bible says, the diameter is 5 meters and the circumference of 15:
circumference = diameter × π -> 15 = 5 × π
with which the value of π is 3.
This calculation of Pi is a bad approximation to the real value. The figure of 3 in the Bible compared with the real one which is 3.1416 ... indicates an error of about 6%.
You would use v=lwh (volume= length x width x height)
Answer:
Step-by-step explanation:
Given that,
Height of the cylinder, h = 6 mm
Radius of the cylinder, r = 4 mm
We need to find the volume of the cylinder. The formula for the radius of the cylinder is given by :
Putting given values,
So, the volume of the cylinder is 
.
