Ohh thank you. The question says to find the length of tangent from the center of one circle to the other, I thought it meant from one center to the other center. The question wasn't clear to me.

Hello Sir, please help me with the below 2 questions:

 

Q1) Two circles of radii 14 and 22 units are 45 units apart at the centers. What is the length of their common internal tangent?

 

Q2) A square whose area is 64 is partitioned into four congruent smaller squares. Find the circumference of the circle that passes through the centers of the four subsquares.

Sir, how do we know that angle CAB is 60°? 

Or if I put it in different term- how do we know that triangle ABC is an equilateral triangle? 

 

Please help.

AC and  AB are circular arcs so 

AC = AB = BC = r ( Radii ) 

Hence , ABC is an equilateral triangle .

In the rectangle ABCD , the perpendicular bisector of AC divides the longer side AB in a ratio 2:1 . Then the angle between AC and BD is?

Sir the figure is troubling me

Hello Richa , 

All the options seem wrong the correct answer is 10 - 2sqrt{15}

Join E - A and D - A 

the angle formed ( EAD ) will be 30º

So the angle formed by the side of the square  at center = 60º 

Hence,  Equilateral triangle 

Radius = Side of the square = 2

Sir, can you help me with the diagram of this question? I'm not able to visualize or draw the diagram.

AB and CD are perpendicular to a diameters of Circle O. Let CM be a chord that intersect AB at E, so that CE=6 and EM =5. Find the circumference of the circle.
