A) 1.9
B) 0.95
C) 2.9
D) 1.45
E) 1.95
Correct Answer: B
Solution :
Distance between the lines\[3x-4y+5=0\]and\[6x-8y-9=0\]is \[\left| \frac{5+\frac{9}{2}}{\sqrt{{{3}^{2}}+{{4}^{2}}}} \right|=\left( \frac{19}{10} \right)=1.9\] is the diameter of circle \[\therefore \]Radius of circle \[=\frac{1.9}{2}=0.95\]You need to login to perform this action.
