[SOLVED] Finding the Radius of Circle Given the Tangent Line and a Center Point
Pretty much I think I solved it while typing the description (Happy)
(h , k) = 4,11
What I Want To Know:
How do you determine the radius?
I couldn't find what I was looking for in the book, so the past 20 minutes I've been trying to solve it with what I understand. The distance from the center point and the tangent line will be the shortest possible distance between the center point and any point on the line. The line segment I believe will be perpendicular so the slope of the line segment should be the negative reciprocal. Knowing this I would need to find out when the perpendicular line meets the center point and at what point the line touches the tangent line.
At least if my logic is straight.
What is best way to determine this?
