Question

How do you solve this problem?
x (squared) + y (squared) = 3/4

Answer 1

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
