36. THE CLASS - ROOM BUDDIES
Manik and Dhruv are bench - mates in the class. In the mathematics class,
Manik was finding that it was difficult to simplify ("5~ \12)' His bench -
mate Dhruv gave him a clue to rationalize the denominator by taking the
conjugate of ( vs' - ..fi). Manik simplified the expression and thanked
Dhruv for the help. Dhruv also gave him the approximate value of -Is' =
2.236 and -Jz = 1.414 to find the approximate value of the expression.

Read the text carefully and answer the questions:
Once upon a time in Ghaziabad was a com cob seller. During
the
lockdown period in the year 2020, his business was almost lost.
So, he started selling com grains online through Amazon and Flipca
rt.
Just to understand how many grains he will have from one com
cob, he
started counting them.
Being a student of mathematics let's calculate it mathematically
. Let's
assume that one com cob (see Fig.) shaped somewhat like a cone,
