Answer :
The length of the radius of a circle with the equation x² + y² = 121 is 11 units .
In the question ,
it is given that ,
the equation of the circle is ⇒ x² + y² = 121 ,
we know that the general equation of the circle is given as x² + y² = d² ;
and "d" is the radius of circle ,
On comparing both the equations ,
we get ,
d² = 121
Simplifying the above equation further ,
on taking square root on both the sides ,
we get ,
d = √121 = √(11 × 11)
the radius "d" is
d = 11 units .
Therefore , the radius of the circle is = 11 units .
The given question is incomplete , the complete question is
What is the radius of a circle with equation x² + y² = 121 ?
