Question

Two concentric circles intersect at…………number of points.
A. 2
B. 0
C. 1
D. None of these.

Answer 1

Hint: A circle is a round-shaped geometrical part, it can be constructed using a measurement called radius r and a point called center. The diameter of the circle is the 2 times the radius of the circle. The radius can be defined as the line that touches the center of the circle and any one point on the circle. It should be kept in mind that the diameter is the largest chord in the circle that touches two points of a circle while passing through the center.

Complete step-by-step answer:

Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus. Any two circles can be made concentric by inversion by picking the inversion center as one of the limiting points.
The term concentric circle means that the circle that is drawn one above another with a different radius of diameter.We can observe the diagram, the concentric circles will consist of the same center denoted as O, which is required to draw the two circles, and we need the radius or diameter to draw the circle.So the two concentric circles did not have any intersecting points in its construction. It has only one center point, which is required to draw them.Therefore, the two concentric circles have zero intersecting points; it means the option (D) is correct.
So, the correct answer is “Option D”.

Note: We are very clear about the terms concentric, similar, and many other terms, because they will differ in the construction of any shape. As per the question, the concentric circles means, the circles that have different sizes but same center to draw them or the circles drawn one above the other but consists of a single center of point.
