Question 144892: This circle is centered at the origin, and the length of its radius is 3/4. What is the equation of the circle.
my response was x^2+y^2=3/4
but it came out as wrong... the other options are ...
x^2/3 + y^2/4=1
or
(x-3)^2+(y-4)^2=25
0r
x^2+y^2=(3/4)^2

It's x%5E2+%2B+y%5E2+=+r%5E2
So the answer is x%5E2+%2B+y%5E2+=+%283%2F4%29%5E2
or, x%5E2+%2B+y%5E2+=+9%2F16
