How many circles can be drawn through 10 points?

The number of circles that can be drawn out of 10 points of which 7 are co-linear. But the answer is 85.

How many circles can be drawn from the Centre of a circle?

Infinite number of circle can be drawn from the centre of the circle.

How many quadrilaterals can be formed from 10 points no three of which are collinear?

10 points lie in a plane, of which 4 points are collinear. Barring these 4 points, no 3 of the 10 points are collinear. How many distinct quadrilaterals can be drawn? Adding them up I got 185 ways, but the answer is 209, which I don’t understand how.

How many lines can be drawn with 18 points on a circle?

→ x = 153 lines (Ans.)

How many lines can be drawn through 3 points on a circle?

Solution : (i) Infinite line can be drawn through a given point. (ii) Only one line can be drawn through two given point. (iii) Only one line can be drawn through three collinear points.

How many circles can be in a circle?

There are an infinite number of real numbers between 0 and 1, or between any two numbers. Each of those numbers is the radius for the circle inside. So an infinite number of circles inside any circle.

Is it possible that many circles have one centre?

It is not possible. A circle has only one centre.

How many quadrilaterals can be formed?

From any vertex you can form 8 triangles or 4 quadrilaterals. Considering all the 10 vertices one can form 10*4 = 40 quadrilaterals.

How many quadrilaterals are determined by 8 points no three of which are collinear *?

Since no three points are collinear , every pair of points determines a distinct line . There are (82)=28 such lines.

How many circles can be drawn to pass through two given points?

We can draw infinitely many circles passing through two given points. Starting from the two points as a diameter, we can draw a circle. As the circle is moving up it becomes a chord to the next circle with a bigger diameter. In such a way, we can draw an infinite number of circles passing through two points.

How many circles can be drawn from a point?

Infinite number of circles pass through a point.

How do you find the number of lines formed from non-collinear groups?

Second, the lines formed using only the points of the non-collinear group – 6 C 2 or 15 lines. Third, select one point from the collinear group ( 4 C 1 ways) and the other from the non-collinear group ( 6 C 1 ways) – the number of such lines will be 4 C 1 x 6 C 1 = 24.

How many lines can be formed from 10 distinct points?

The number of ways to select any points (out of 10 distinct points) will be 10 C 2. Once we select the points, there is only 1 straight line which will be formed using these points. Therefore the number of lines will be 10 C 2 x 1 or 45. Here’s a crazy figure to illustrate.

What are the different types of permutations?

Permutations are of two types: Combinations are also of two types: In Chapter 7, students will learn to solve exemplar problems based on the topics given below; 1. Eight chairs are numbered 1 to 8. Two women and 3 men wish to occupy one chair each.

What is permutations and combinations of NCERT exemplar solutions for Class 11?
