Answer:
( x - 0 )² + ( y - 0 )² = 5²
Step-by-step explanation:
Given :
Equation of circle :
x² + y² - 25 = 0
We know standard equation of circle :
( x - h )² + ( y - k )² = r²
Where ( h , k ) is centre of circle and 'r' is radius of circle
= > x² + y² - 25 = 0
Adding two zeroes .
= > x² + 0 + y² + 0 - 25 = 0 + 0 + 0
Rewrite as :
= > ( x - 0 )² + ( y - 0 )² - 25 = 0
= > ( x - 0 )² + ( y - 0 )² = 25
= > ( x - 0 )² + ( y - 0 )² = 5²
Therefore we get standard equation of circle.
Radius of circle = 5 units
Centre of circle is ( 0 , 0 ) .
