Question

(4)If edge of a circle is ‘a’,then the length of its diagonal is:....
1.a√2 2.a√3 3. a√5 4. 6a²​

Answer 1

Answer:

a root 3 is the answer

Step-by-step explanation:

We can find the solution of this question using pythagoras in 2 different triangles and combine them, but there is a quick derived formula for all questions like these.

The length of the diagnol in a cuboid= Whole Under root of l^2+b^2+h^2

So in this case it becomes whole undder root of 3a^2

=a square root 3
