How do I find the radius of a circle that contains the point (12,15)
To find the radius of a circle that contains a given point, you need to know the coordinates of the center of the circle.
Let's say the center of the circle is (x, y). The radius (r) is the distance between the center and any point on the circle. In this case, since we are given a point on the circle (12, 15), we can use the distance formula to find the radius.
The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this formula, (x1, y1) represent the coordinates of the center of the circle (x, y), and (x2, y2) represent the coordinates of the given point (12, 15).
Substituting the values into the formula, we get:
d = sqrt((x - 12)^2 + (y - 15)^2)
Since we want to find the radius, the distance (d) is equal to the radius (r). So the equation becomes:
r = sqrt((x - 12)^2 + (y - 15)^2)
To find the radius, you will need to know the coordinates of the center of the circle, which are not provided in your question.
