If the question asking you to find a tangent to a circle, the equation of the circle should be given, let say C: x^2 + y^2 + 2dx + 2ey + f = 0 where d, e, f are constants. Since there are infinitely many tangent to the circle, to find a specific tangent required at least one additional information given by the question.... The equation for calculating the area of an ellipse is similar to that for calculating the area of a circle, with the only difference being the use of two radii, rather than one (since the foci are in the same location for a circle):

## How To Work Out The Equation Of A Circle

Cable diameter to circle cross-sectional area and vice versa Round electric cable , conductor , wire , cord , string , wiring , and rope Cross section is just a two-dimensional view of a slice through an object.

- Well, from the area, we could figure out what the radius is, and then from that radius, we can figure out what its circumference is. So we know that the area, which is 36pi, is equal to pi r squared. And so if you look at it on both sides of this equation, if we divide-- let me rewrite it so it's a little bit clearer in a different color. So we could set up an equation …
- 14/05/2008 · Best Answer: If you want something to remember, then think generally. Suppose its a more general equation for a circle: (x-a)^2 + (y-b)^2 = c^2. 1. Then to get the points where it crosses the y axis, solve for x=0. So in the general case y = b + sqrt(c^2 - a^2) and y = b - sqrt(c^2 - …

- The circle’s equation is expressed in four algebraic forms when the circle is touched the vertical axis at a point. 2. According to distance between two points. The distance from centre of the circle to any point on the circumference is equal to the radius of the circle. The distance between these two points can be found by using a geometrical formula and equal the distance between them to
