#### Area of the circle in which a chord of length makes an angle p/2 at the centre is

Let AB be the chord of length , O be the centre of the circle and let OC be the perpendicular from O on AB. Then AC = BC =

In DOBC, OB = BC cosec 45° =

\ Area of the circle = p (OB)

Hence (c) is the correct answer.

In DOBC, OB = BC cosec 45° =

\ Area of the circle = p (OB)

^{2}= p.Hence (c) is the correct answer.

#### Equation of a circle with centre (4, 3) touching the circle is

Let the circle touching the circle x

The equation of the common tangent is S

i.e. 8x + 6y–1–k = 0

This is a tangent to the circle x

Hence ± 1 =

Þ k+1 = ± 10 Þ k = –11 or 9

Therefore the circles are x

Hence (d) are the correct answers.

^{2 }+ y^{2}= 1, be x^{2 }+ y^{2 }– 8x – 6y + k = 0,The equation of the common tangent is S

_{1}– S_{2}= 0i.e. 8x + 6y–1–k = 0

This is a tangent to the circle x

^{2}+y^{2}= 1.Hence ± 1 =

Þ k+1 = ± 10 Þ k = –11 or 9

Therefore the circles are x

^{2}+y^{2}–8x–6y+9 = 0 and x^{2}+y^{2}–8x–6y–11 = 0Hence (d) are the correct answers.
