Question

a circle drawn with origin as the centre passes through (5,0). the point which does not lie in the interior of the circle is

Answer 1

Given: A circle drawn with origin as the centre passes through (5,0).

To find: The point which does not lie in the interior of the circle.

Solution:

• Now we have given that the centre is taken as origin (0,0).

• It is provided that circle passes through the point (5,0), which means the radius is at distance (5,0).

• Let the distance be x.

• Now the distance from centre to (5,0) is:

                     x = √(x2-x1)² + (y2-y1)²

                     x = √(5-0)² + (0-0)²

                     x = √25

                     x = ±5

• Now -5 will be discarded as distance is taken positive always.

• So the point which has a distance less than 5 cm, they will be inside the circle.

Answer:

                 So the point which has a distance less than 5 cm, they will be inside the circle.
