If the point (x ,4) lies on a circle whose centre is at the origin and radius is 5, then x= +-5 (b) +-3 (c) 0 (d) 14

If the point (x,4) lies on a circle whose centre is at the origin and radius is 5, then x=+-5 (b) +-3(c)0(d)14

Points A (-1, y) and B (5, 7) lie on the circumference of a circle with centre O (2,-3y). Find y. Hence find the radius of the circle.

Points A(-1,y) and B(5,7) lie on a circle with centre O(2,-3y). Find the values of y Hence,find the radius of the circle.

Points A(-1, y) and B(5, 7) lie on a circle with centre O(2, -3y) . Find the values of y. Hence, find the radius of the circle.

Make a point P and draw a circle with centre P and radius 5 cm. Take any point Q on the circle drawn. With Q as centre and radius 3 cm draw another circle. Label the two points at which the circles intersect as A and B. Join PQ and AB. Find the angle between AB and PQ.

Find the radius of a circle whose centre is at the origin and a point P(5, 0) lies on its circumference.
