Question

equation of a standard circle is x²+y²=r². It's centre is at (0,0) and radius is r. ​

Answer 1

Answer:

ANSWER

Compare the equation with the standard form with center at (h,k) and radius r is: (x−h)

2

+(y−k)

2

=r

2

Substitute the value of (h,k)=(0,0) and r=5

Then, the equation becomes x
