Answer:
1/5
Step-by-step explanation:
The best way to think about this is on a number line. -4 would be on the left of 0 meaning it is less than 0 and is on the right side of 0 but it is less than 1.
Therefore, the equation of circle is:
- All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
- The radius of a circle is the separation between any point on the circle and its center.
- The radius must typically be a positive integer. Except when otherwise specified, this article discusses circles in Euclidean geometry, namely the Euclidean plane.
- A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior.
Here we know thatbut we are not given the radius.
However, we can find the radius by using the distance formula.
, where
and
Putting the values, we get:
The radius comes out to be:
An equation of the circle with center and radius r is
Now, substituting the values, we get:
Therefore, the equation of circle is:
