If the lines `3x-4y-7 = `0 and `2x-3y-5=0` are two diameters of a circle of area `49pi` square units, the equation of the circle is:

Explanation

Given Equations of diameter :`3 x-4 y-7=0 ldots ldots (1) `


`2 x-3 y-5=0 ldots ldots (2)`


Solving equations


`3 x-4 y-7=0 quad times 2 `


`2 x-3 y-5=0 times 3 `


`6 x-8 y-14=0 ldots (3) `


`6 x-9 y-15=0 ldots (4)`


Subtract equation (3) from (4),
