The equation of the circle which touches the x- axis and whose centre is (3, 4) is
The study of conic sections helps in understanding the shapes formed by the intersection of a plane with a double-napped cone. The CBSE 2024-2025 NCERT Class 11th syllabus includes this chapter to introduce students to different curves like circles parabolas ellipses and hyperbolas. It covers standard equations properties and real-life applications of these curves. Multiple-choice questions are provided to test conceptual clarity and improve problem-solving accuracy. Regular practice of these MCQs enhances logical thinking and mathematical skills. A strong understanding of conic sections is essential for mastering coordinate geometry and excelling in board as well as competitive exams.
Choice (a) is correct.
As the coordinates of the centre are (3, 4) and radius = 4 because distance of a point (on x-axis) on a circle from the centre (3, 4) is the y-coordinates i.e., 4 so, the required equation is (x – 3)² + (y – 4)² = 4²
This question related to Chapter 10 maths Class 11th NCERT. From the Chapter 10: Conic Section. Give answer according to your understanding.
