What is the radius of a circle with equation x² y² 121?

Sagot :

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 .
