Question

Give the equation of the circle centered at the origin and passing through the point (-11, 0)

Answer 1

the equation for the circle is:

X² +Y² = 11² = 121

Answer 2

Explanation:

Since we know the general circle equation is in the form

x^2 + y^2 = r^2, where r is radius

Now we are given the information that circle has the origin (0,0) and pass through point (-11,0), which mean the radius is 11 units.

Now we can write the circle equation as

x^2 + y^2 = 11^2
