The equation of the circle whose radius is 3 and which touches the circle x2 + y2 – 4x – 6y – 12 = 0 internally at the point (–1, –1) is-
- \(\left(x-\frac{4}{5}\right)^{2}+\left(y+\frac{7}{5}\right)^{2}=3^{2}\)
- \(\left(x-\frac{4}{5}\right)^{2}+\left(y-\frac{7}{5}\right)^{2}=3^{2}\)
- (x–8)2 + (y–1)2 = 32
- None of these
Answer
(B) (x- 4 5 )^ 2 + (y- 7 5 )^ 2 =3^ 2
