Answer :
The length of the radius of a circle with the equation x² + y² = 8 is 2√2 units .
In the question ,
it is given that ,
the equation of the circle is ⇒ x² + y² = 8 ,
we know that the general equation of the circle is given as x² + y² = b² ;
and "b" is the radius of circle ,
On comparing both the equations ,
we get ,
b² = 8
Simplifying the above equation further ,
we get ,
b = √8 = √2 × 2 × 2
the radius "b" is
b = 2√2 units .
Therefore , the length of the radius of the circle is 2√2 units .
The given question is incomplete , the complete question is
