WebOct 5, 2024 · (x-h) 2 +(y-k) 2 =4 2. Since it is tangent to the x-axis, y=0 at that point. Also, since it has the point (-5,8) on its perimeter, the circle is above the x-axis (if it goes as high as y=8 and it's radius is only 4, then the circle must be above the x-axis). But if it is tangent to the x-axis, AND its diameter is 8, then (-5,8) MUST be at the ...

WebAug 17, 2015 · The point of tangency will be the closest point to the circle on the X Axis. As a rule of thumb, the shortest distance between a point (3,4) and a line (x=0) will be perpendicular to the line and run through the point. In this case, graph a vertical line that goes through your point (3,4) and you'll see that it hits the X Axis at (3,0). WebSep 26, 2016 · Since the circle is tangent to the x axis , its radius have to be r = 13. This means that the distance from one y intercept, e.g ( 0, − 8) is such that: ( 0 − α) 2 + ( − 8 + 13) 2 = r 2 = 169 solve this for α and you have two circle.

WebSince the point on $y$ tangent to the circle (I'll call it $Y$) is $ (0,Y)$ and on $x$ (I'll call it $X$) is $ (X,0)$. Let's call the center $E$. From $X$ to $E$ and $Y$ to $E$ are the radii. So $XE=YE$. Then I'll use the distance … WebDec 18, 2024 · Now, as for the radius, and the circle being tangent to the y-axis. This means it has to touch the y -axis at some point. In other words, the size of the radius should be set in a way such that there is exactly one point on the circle that is on the y -axis (has an x value of 0 ).
WebJul 31, 2012 · Your method of calculating the radius (if D is supposed to be the radius) makes no sense. The problem is actually very simple. You're given that the circle is tangent to x=13, which is a vertical line. You know the centre has an x-coordinate of 10. So what can you say about the radius? Jul 30, 2012 #4 xxmegxx 3 0 I meant D to be the distance. WebOct 30, 2016 · The standard form of the equation of a circle is: (x −h)2 + (y −k)2 = r2 where (h,k) is the center point and r is the radius Substitute the center point (4,2) into the standard form: (x −4)2 + (y −2)2 = r2 Because the center is 2 units above the x axis and the circle is tangent to the x axis, the radius must be 2: (x −4)2 + (y −2)2 = 22 Answer link
WebSince the tangent line to a circle at a point P is perpendicular to the radius to that point, theorems involving tangent lines often involve radial lines and orthogonal circles. The tangent has two defining properties such as: A Tangent touches a circle in exactly one place. The Tangent intersects the circle’s radius at
