Answer:
The radius of circle is 4
Step-by-step explanation:
Given as :
The equation of circle is given as :
x² + y² = 16
Now The standard equation of
( x - h )² + ( y - k )² = r²
where h , k are center of circle
r is the radius of circle
From given circle equation x² + y² = 16 can be written as
( x - 0 )² + ( y - 0 )² = (4)²
So, The center of this circle is ( h , k ) = ( 0 , 0 ) And radius of circle = 4
Hence The radius of circle is 4 Answer
