Here is ur answer in the picture
A thin wire is bent in the form of an equilateral triangle of side 11 cm.If the same wire is bent in the form of circle, find its area.
With the best explanation.
According to the question we know that side of triangle is 11 cm .and triangle is a equilateral triangle so, the length is 11*3 = 33 we, need to find area or radius
Radius of circumference is 2πr
Then, area of circumference is πr²
Find the length of the wire:
Length = 11 + 11 + 11 = 33 cm
Find the radius:
Circumference = 2πr
33 = 2πr
r = 33/2π
r = 5.25 cm
Find the area:
Area = πr²
Area = π(5.25)² = 86.625 cm²
The area is 86.625 cm²
I didn't understand your question
I don't know the answer
Due to the work done against gravity
Our muscles and body need to do work against gravity which leads to usage of energy. This energy is obtained from oxygen ( I won't go in detail in that) which leads to more Breathing as the muscles suddenly need more oxygen. And even simple physics is used.
Change A is physical change - In this change, the liquefied gas changes it states from liquid to gas and hence no new substance are formed.
Change B is chemical change:- Burning produces new substance and hence the reaction can't be reversed back.
That is because whenever you are climbing up the stairs you are doing work against the gravity but when you climb down you do work with the gravity. And doing work against gravity consumes more energy than doing work with the gravity.
i can,t explain nowi will post it in evening
I think so
minute = small
the people in a story are seemed very small in size as comparable to playing toys.
make believe land = an imaginary planet/place
the people seemed to be living in a strange planet but actually the place is looking quite different becoz of things appearing small.
I think that this description is given in a so-called story for Lilliputs ...
note : the above narration may be not relevant if the context is related to an other story. so be sure of that story...
the answer with the best explanation will be marked br...
