πr2h or the radius squared multiplied by pi multiplied by the vertical height of the cylinder.
What was the hardest problem albert instein did?
Oh, dude, like, Albert Einstein probably had a tough time deciding whether to have a bagel or a croissant for breakfast. But seriously, the hardest problem Einstein tackled was probably his theory of general relativity, which revolutionized our understanding of gravity and the universe. Like, no big deal, just reshaping the way we see the world and stuff.
Yes, the time taken to go to the library can be considered a function of the distance to the library. In mathematical terms, a function is a relation between a set of inputs (distance) and a set of possible outputs (time taken). As the distance to the library increases, the time taken to travel there also typically increases, assuming a constant speed of travel. This relationship between distance and time aligns with the definition of a function, making it a valid example of a functional relationship.
Who is the father of probability?
The father of probability is considered to be Blaise Pascal, a French mathematician, physicist, and philosopher. Pascal made significant contributions to the development of probability theory in the 17th century, particularly through his correspondence with Pierre de Fermat. Together, they laid the groundwork for the modern understanding of probability and its applications in various fields such as mathematics, statistics, and economics. Pascal's work on probability, including the famous Pascal's Triangle, remains fundamental in the study of random events and uncertainty.

What is the history of the abacus?
The abacus is an ancient calculating tool with a history spanning over 3,000 years. Its name derives from the Greek word "abax" or "abakon," meaning "tabular form," possibly originating from the Semitic word "abq," meaning "sand."
Evolution of the Abacus
Origins (circa 300-500 BC): The exact origin of the abacus is not definitively established, but it is believed to have been invented between 300 and 500 BC.
Chinese Abacus (Suanpan): Early versions featured a 2/5 bead configuration, which was complex and later simplified.
Japanese Abacus (Soroban): Mathematician Seki Kowa modified the abacus to a 1/4 bead configuration, leading to the modern Soroban used today.
Today, the abacus is not only a manual calculator but also a powerful brain development tool. At Mastermind Abacus, we integrate this ancient instrument with modern teaching methodologies to enhance mathematical skills and cognitive abilities in learners.
An abacus is an ancient calculating tool used for fast and accurate arithmetic. It helps in measuring and performing various mathematical operations.

Which is greater 0.099 or 0.1?
O.1 is greater but they are very close to being the same number. If you add zeros to the 0.1 you see that
0.1 = 0.100 and 0.100 is greater than 0.099

What shape is stronger an arch or a triangle?
Oh, dude, are we building a bridge or planning a geometry heist? Well, technically speaking, an arch is stronger than a triangle because it can distribute weight more evenly. But hey, if you're just doodling shapes on a napkin, I don't think it really matters which one you pick.
What is the hardest addition problem?
Different people find different things hard. So a problem that is hard for someone may seem easy to you and one that you think is hard may be easy for someone else. It is, therefore, not possible to answer the question.
Does IX mean 11 in Roman numerals?
NO!!!!
'IX = 9
However 'XI = 11
In Roman numerals
The letters corresponding to their values are
M = 1000
D = 500
C = 100
L = 50
X = 10
V = 5
I = 1
The highest value letter ALWAYS goes to the left , except for subtraction.
So in you example IX , the I =1 is of lesser value than X = 10 . Hence when this lesset value letter is placed to the left of a higher value letter it means 'subtract'. So ;IX' means 10 - 1 = 9 However, 'XI = 10 + 1 = 11
Similarly
MM = 1000 + 1000 = 2000
But
MCM = 1000 + ( 1000 - 100) = 1000 + 900 = 1900.
So the years 2025 is = MMXXV
However the year 1925 = MCMXXV
What is 0.185185185 in a fraction?

What problem for Aristotle was the hardest to overcome?
One of the biggest challenges for Aristotle was reconciling his belief in the eternal and unchanging nature of the universe with the observed phenomena of change and motion in the natural world. This led to his development of the concept of potentiality and actuality to explain how things can change while still maintaining their essential nature. Additionally, Aristotle struggled with defining the relationship between form and matter, particularly in understanding how form can exist independently of matter in the realm of metaphysics.
A geometric figure represented by dot?
Ah, what a delightful question we have here. A geometric figure represented by a dot is known as a point. Just like a tiny speck of paint on our canvas, a point is the simplest element in geometry, yet it holds infinite possibilities for creating beautiful shapes and forms. Embrace the simplicity of a point, for from it, we can create entire worlds of art and imagination.
Was 2 shillings a lot in Victorian times?
Well, honey, back in the Victorian times, 2 shillings was considered a decent amount of money. It could buy you a nice meal or a few pints at the pub. But let's be real, it wasn't exactly a fortune. Just enough to keep you out of the poorhouse for a day or two.
Oh, dude, Baravelle Spirals are these cool geometric patterns that occur naturally in some fruits and vegetables when you cut them a certain way. It's like nature's way of saying, "Hey, check out my fancy math skills!" So next time you're slicing up a cabbage or a Romanesco broccoli and see those intricate spirals, just remember, nature's got some serious style.
73 is 20 percent of what number?
To find the number that 73 is 20% of, you can set up a proportion:
73 = 0.20x
To solve for x, you would divide both sides by 0.20:
x = 73 / 0.20
x = 365
Therefore, 73 is 20% of 365.
To determine the greatest number of crayons in each row of the boxes, we need to find the greatest common factor of the total number of crayons in each box and the number of rows. The factors of 8 are 1, 2, 4, 8. The factors of 64 are 1, 2, 4, 8, 16, 32, 64. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96. Therefore, the greatest number of crayons in each row for the 8, 64, and 96 crayon boxes is 4.
How do you know the woman at the next table in the resturaunt is a math teacher?
You can infer that the woman at the next table is a math teacher based on observable cues such as her attire, accessories, and behavior. Math teachers often wear clothing or jewelry with mathematical symbols or motifs, carry math-related items like textbooks or calculators, and may engage in conversations or activities related to mathematics. Additionally, if she is grading papers or working on math problems, it further supports the assumption that she is a math teacher.
