How do you solve this problem?

x (squared) + y (squared) = 3/4

Equation of a circle is:

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

where coordinate (h, k) is the center

and r is the radius

we can make the given equation look like this:

(x-0) ^2 + (y-0) ^2 = (sqrt (3) / 2) ^2

from here we can see that the center is (0, 0)

and the radius is square root (3) / 2
