Chapter 11: Q. 11.21 (page 1081)

(a).Find the center and radius,then
(b).Graph the circle $x^{2} + y^{2} - 2 x - 3 = 0$

Short Answer

Expert verified

(a).Center $c = (1, 0)$ and radius $r = 2$

(b).Graph of the circle.

Step by step solution

Part(a).Step 1.Given information

The equation of the given circle $x^{2} + y^{2} - 2 x - 3 = 0$

We have to find radius and center.

Also, we have to graph this circle.

Part (a) Step 2. Converting into standard circle form

find the values of x and y- terms,

$(x^{2} - 2 x) + (y^{2}) = 3 (x^{2} - 2 x + 1) + (y^{2} - 0) = 3 + 1 {(x - 1)}^{2} + {(y - 0)}^{2} = 2^{2}$

Which is the standard circle form with

circle= $(1, 0)$

radius = $2$

Part b.Step 1.Given information

The equation of the given circle $x^{2} + y^{2} - 2 x - 3 = 0$

Part b.Step 2.Graph of the circle.
