Question

A park is designed in form of a circle.at centre there is a fountain. The entry gate is shown at A
Consider coordinate of fountain (centre 0) of circle is (29 -1, 7) and coordinate of point A is (-3, -1).
(a) I radius of circle is 10 units, then possible values of a are
(1) 4,2
(ii) - 4,2
(in) 4,-2
(iv) - 4, - 2
(b) Distance AB -
(0) 10 units
(ii) 20 units
(iii) 10/2 units
(iv) 5 units
() If we consider, point A lies on x-axis, the what is the possible value of x-coordinate of A, take a = 2
(iii) -3+V51
(iv) 3
(d) If we consider, point B lies on y-axis then what is the possible value of y-coordinate of B take a = 2
(1) 7691
(11) -74791
(iv) -7
(e) AOB form an
() equilateral triangle
(11) isosceles right angled triangles
(ili) scalene triangle
(iv) collinear points​
