Write an equation of the circle with center (-7, 4) and radius 3.

Explanation: The formula for the equation of a circle is shown below.

In the equation above, hk is the center and r is the radius.

Since we are given that the center is (-7, 4) which represents (h, k) and the radius is 3 which represents r,

we simply plug these values into the formula.

So we have [x - (-7)]² + [y - (4)]² = 3².

Notice that I changed the parentheses that were in the original formula to brackets so that we wouldn't have too many sets of parentheses when plugging our values into the formula.

Finally, we simplify inside the brackets.

[x - (-7)] simplifies to [x + 7].

So we have (x + 7)² + (y - 4)² = 9.

Notice that I changed the brackets back to

parentheses in the final answer.

So the equation of a circle with center (-7,4)

and radius 3 is (x + 7)² + (y - 4)² = 9.
