Story of Pi
In math, "pi" (often written as the Greek letter π) is a number that represents the ratio of a circle's circumference (the distance around the circle) to its diameter (the distance across the circle through its center). No matter how big or small the circle is, this ratio is always the same and approximately equal to 3.14159.
To put it simply, if you take a string and wrap it once around a circle, then lay that string out straight, it would be a little more than three times the length of the circle's diameter. This "little more" is the extra decimal places of pi. Pi is an irrational number, meaning it goes on forever without repeating.
Now, what is irrational number? Will post in second lesson.
In mean while try the above and let me know.

Rational Numbers?
In simple English, "rational" means something that is logical or makes sense. In mathematics, rational numbers are related to the concept of fractions. Let's travel back and review the lesson on fractions, specifically proper and improper fractions.
Proper fractions are fractions where the numerator (the top number) is smaller than the denominator (the bottom number). For example, 3/4
is a proper fraction.
Improper fractions are fractions where the numerator is larger than or equal to the denominator. For example, 5/3
is an improper fraction.
Both proper and improper fractions are members of the rational number family. Rational numbers are numbers that can be expressed in the form a/b
, where
𝑎 and 𝑏 are integers, and 𝑏 is not zero.
Now, what happens if the denominator becomes zero? What kind of fraction is that? Is it making any sense? No, it doesn't. Dividing by zero is undefined and does not produce a valid number. Therefore, rational numbers must have a denominator that is not zero. When you divide rational numbers, you get definite decimal places that either terminate or repeat.
In summary, rational numbers are fractions where the denominator is never zero, and their decimal expansions are predictable—they either end or follow a repeating pattern.

Indian farmers to grow commercial crops like indigo for British Industries, which led to agriculture turning commercial and caused a shortage of food grains.
Ans: India witnessed the growth of some industries before independence, the most prominent of which is Tata Iron and Steel Company (TISCO). India was also witnessing a growth of textile mills and ancillary products. Maharashtra, Gujarat, and Bengal were areas where cotton and jute industries were set up. Apart from these industries, some other industries that started operating are sugar, paper and cement.

Given, the actual path length travelled is 23 km, displacement is 10 km and the time taken is 28 min.
(a)
Average speed of the taxi is given as,
v avg = Total Path length Time
Here, s is the total path length
Substitute the values in above equation.
v avg = Total Path length Time = 23 km ( 28 min )( 1 h 60 min ) =49.3 km/h
Hence, the average speed of the taxi is 49.3 km/h .
(b)
Magnitude of the average velocity is given as,
v avg = Displacement Time
Substitute the values in the above equation.
v avg = Displacement Time = 10 km ( 28 min )( 1 h 60 min ) =21.4 km/h
(c)
From the calculation in (a) and (b), it is obtained that the average speed is not equal to the magnitude of average velocity.

Hydrogen peroxide in acid solution is oxidized with KMnO4 and reduced with KI. When H2O2 serves as an oxidizing agent, the oxygen is reduced to H2O. When H2O2 serves as areducing agent, the oxygen is oxidized to O2 and bubbles are noticed.
