Question

Radius of a circle with centre 'O' is 5 cm. Length of the segment OD = 9 cm. Where does the point D lie?

• A. Point D lies outside the circle
• B. Point D lies inside the circle.
• C. Point D lies on the circle.
• D. Point D is the centre of the circle.

Answer 1

The correct option is A

Point D lies outside the circle

The part of the plane, or the set of points in a plane that lie inside a circle is called the Interior of the circle.

The point of plane, or the set of points in a plane, that lie outside the circle is called exterior of a circle.

M, N, P, Q $\to$ lie inside the circle.

T, S, R $\to$ lie outside the circle.

In the given question, OD = 9 cm, radius = 5 cm. The point D lies outside the circle as OD = 9 cm, which is greater than the length of the radius.
