Question

The equation of a circle whose center is (3,7) and whose radius is 6 is

Answer 1

The equation of any given circle is:

`{(x - h)}^(2) + {(y - k)}^(2) = {r}^(2)`
where (h, k) is the center and r is the radius.

In the problem, we are given the center, and the radius. When we plug them in:

`{(x - 3)}^(2) + {(y - 7)}^(2) = 36`
we got the formula of the circle.
