conic section ncert book full solution conic section exercise full solution ]]]]™℗   Solutions for Class 11 Maths Chapter 11 EXERCISE 11.1 PAGE NO: 241 In each of the following Exercise 1 to 5, find the equation of the circle with 1. Centre (0, 2) and radius 2 Solution: Given: Centre (0, 2) and radius 2 Let us consider the equation of a circle with centre (h, k) and Radius r is given as (x – h) 2  + (y – k) 2  = r 2 So, centre (h, k) = (0, 2) and radius (r) = 2 The equation of the circle is (x – 0) 2  + (y – 2) 2  = 2 2 x 2  + y 2  + 4 – 4y = 4 x 2  + y 2  – 4y = 0 ∴ The equation of the circle is x 2  + y 2  – 4y = 0 2. Centre (–2, 3) and radius 4 Solution: Given: Centre (-2, 3) and radius 4 Let us consider the equation of a circle with centre (h, k) and Radius r is given as (x – h) 2  + (y – k) 2  = r 2 So, centre (h, k) = (-2, 3) and radius (r) = 4 The equation of the circle is (x + 2) 2  + (y – 3) 2  = (4) 2 x...
