Question : What is the ratio of inradius and circumradius of an equilateral triangle?

Option 1: 1 : 2

Option 2: 1 : 3

Option 3: 1 : 4

Option 4: 3 : 2

Team Careers360 21st Jan, 2024

Correct Answer: 1 : 2


Solution : Let $a$ be the side of the equilateral triangle.
Circumradius = $\frac{abc}{4 \times \text{Area of triangle}}$, where $a,b,c$ are sides
In Case of equilateral triangle, abc = a3 and area of triangle = $\frac{\sqrt{3}a^{2}}{4}$
$\therefore$ Circumradius = $\frac{a^{3}}{4 \times \frac{\sqrt3a^{2}}{4}}=\frac{a}{\sqrt{3}}$
Inradius =

Option 2: $26 \sqrt{3} \mathrm{~cm}$

Option 3: $23 \sqrt{2 } \mathrm{~cm}$

Option 4: $46 \mathrm{~cm}$

Question : Comprehension:
Read the given passage and answer the questions that follow.
My grandmother, like everybody’s grandmother, was an old woman. She had been old and wrinkled for the twenty years that I had known her. People said that she once had been young and pretty and had even had a husband, but that was hard to believe. My grandfather’s portrait hung above the mantelpiece in the drawing room. He wore a big turban and loose-fitting clothes. His long, white beard covered the best part of his chest, and he looked at least a hundred years old. He did not look the sort of person who would have a wife or children. He looked as if he could only have lots and lots of grandchildren. As my grandmother being young and pretty, the thought was almost revolting. She often told us of the games she used to play as a child. That seemed quite absurd and undignified on her part, and we treated it like the fables of the prophets she used to tell us.
