Question

Which of the following gives the equation of a circle of radius 22 and center at the point (-1,2)(-1,2)?

Answer 1

Explanation:

Equation of a circle is

`(x - h) {}^(2) + (y - k) {}^(2) = {r}^(2)`

where (h,k) is the center

and the radius is r.

Here the center is (-1,2) and the radius is 22

`(x + 1) {}^(2) + (y - 2) {}^(2) = 484`
