Radius of circle with centre at `(2,1)` & which has a chord trisected at `((1)/(3),(1)/(3))` ,`((8)/(3),(8)/(3))` is

((1)/(2)x^((1)/(3))+x^(-(1)/(3)))^(8)

(7)/(8)+(3)/(4)((1)/(2))(2)/(3)-(1)/(3))

The equation of the circle with centre at (1, 3) and radius 3 is

If a chord of the circle x^(2)+y^(2)-4x-2y-c=0 is trisected at the points ((1)/(3),(1)/(3))&((8)/(3),(8)/(3)), then 'c' equal to: 10 (b) 20( c) 40 (d) none of these

(7)/(8)-(3)/(4)+(1)/(2)=(7-3+1)/(8)=

The radius of the circle with centre at (3, 2) and whose common chord with the cirlce C:x^(2)+y^(2)-4x-8y+16=0 is also a diameter of the circle C, is

Find the equation of the circle with centre(-1,-3) and radius sqrt3

6(3)/(8)-3(1)/(16)+5(1)/(8)=?
