Topics Covered in Exercise 10.1 Class 11 Mathematics Questions
Ex 10.1 class 11 maths ch 10 is based on sections of a cone, degenerated conic sections and circle. You will get to know the detailed solutions of every topic from this exercise provided by our subject expert of eSaral.
1. 
Sections of a Cone 

2. 
Circle 

Sections of a Cone
If we take the intersection of a plane with a cone, the section obtained is called a conic section. Thus, conic sections are the curves obtained by intersecting a right circular cone by a plane.
We obtain different kinds of conic sections depending on the position of the intersecting plane with respect to the cone and by the angle made by it with the vertical axis of the cone.
The intersection of the plane with the cone can take place either at the vertex of the cone or at any other part of the nappe either below or above the vertex. We made four different kinds of conic sections, namely: Circle, ellipse, parabola and hyperbola.

Circle, ellipse, parabola and hyperbola
When the plane intersects the nape of the cone (other than the vertex), we get the following situations:
(a) When β =90^{o} , the section is a circle.
(b) When α < β < 90^{o} , the section is an ellipse.
(c) When β = α; the section is a parabola.
In all three cases, the plane completely cuts across one nape of the cone.
(d) When 0 ≤ β < α; the plane cuts through both the nappes and the curves of intersection is a hyperbola.

Degenerated conic sections
When the plane cuts at the vertex of the cone, there are the following different situations:
(a) When α < β ≤ 90^{o} , then the section is a point.
(b) When β = α, the plane contains a generator of the cone and the section is a straight line.
It is the degenerated case of a parabola.
(c) When 0 ≤ β < α, the section is a pair of intersecting straight lines, It is the degenerated case of a hyperbola.

Circle  A circle is the set of all points in a plane that are equidistant from a fixed point in the plane.
The fixed point is called the centre of the circle and the distance from the centre to a point on the circle is called the radius of the circle.
With the Given (h, k) be the centre and r the radius of the circle, the equation of circle is
(x – h)^{2} + (y – k)^{2} = r^{2}

Frequently Asked Questions
Question 1. What is a circle? write the equation of a circle.
Answer 1. A circle is the set of all points in a plane that are equidistant from a fixed point in the plane. The equation of the circle is (x – h)^{2} + (y – k)^{2} = r^{2}.
Question 2. What is the conic section in NCERT solutions class 11 maths chapter 10 ex 10.1?
Answer 2. If we take the intersection of a plane with a cone, the section obtained is called a conic section. There are four main types of conic sections in geometry that are Ellipse, Circle, Parabola and Hyperbola.
