chetan2u The maximum distance between ANY POINT on the circle and C must be twice of radius plus distance between C and P where P is the point on circle while joining C and O. Am I right with this ?
Posted from my mobile device Yes you are right..
Because we know AC and AO, we will know CO..add the radius and we can get our answer..
\(\sqrt{9^2+5^2}\)+5
Hi
chetan2u,
I am unable to get this question!
It says maximum distance, so it has to be either A or B cos they intersect the circle at one point.
First statement gives u Radius but you are not sure cos length of hypotenuse can be anything not necessarily 13(5-12-13 triangle).
Insuff.
Second says
AC =9 units but we know nothing about CB.
Insuff.
Now, taking them together,
Radius=5, AC=9 cms, therefore, Hypotenuse=SQRT(81+25)=SQRT(106)=10.Something
But we still dont know anything about B.
what if point C is positioned more towards B or A.
Values wont be same, so we wont be able to answer the question the MAXIMUM distance between C and either A or B.
So both are insuff. thus E
I hope i was able to explain my doubt!
Looking forward to your explanation.
