Question

The equation of a circle is given below.

9
x^2+ (y - 7.5)^2 =9/49
What is its center?

Answer 1

(0, 7.5)

Explanation:

Compare the equation to the standard-form equation of a circle:

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . center at (h, k); radius r

You will notice that ...

h = 0

k = 7.5

The center is (h, k) = (0, 7.5).
