Chapter 11: Q.259 (page 1156)

In the following exercises, a) find the center and radius, then b) graph each circle:

3x2+3y2=432

Short Answer

Expert verified

The center of the circle is at(0,0) and radius is at 12

The graph of the circle can be given as

Step by step solution

01

Given information

The equation of the circle is3x2+3y2=432

02

Divide both sides by 3

We get,x2+y2=144

03

Compare With standard equation

Writing in standard form we get, (x-0)2+(y-0)2=122

On comparing we get, the center is at (0,0)

And radius can be given as12

04

Graph the equation

The graph of the circle can be given as

05

Conclusion

The center of circle is at(0,0)and radius is 12.

The graph of the circle can be given as
