Circle touching externally
WebSolution When two circles touch externally, the distance between their center is the sum of their radii. It gives you the system of three equations a + b = 3, (1) a + c = 4, (2) b + c = 3. (3) where a, b and c are the radii of the three circles with the centers A, B and C respectively. To solve the system, first add all the three equations. WebApr 5, 2024 · The second and third tangent is passing from the top and bottom point of both the circles. Therefore, from two circles touching externally, three tangents can pass. So, the correct answer is three. …

Cameron Buie. 101k 9 93 215. Add a comment. 1. A the point of contact the circles share a mutual external tangent and so the two radii are both perpendicular to that line. Therefore the center to center distance is simply r 1 + r 2, in this case 2 + 3 = 5. Share. Cite.
WebLet O be the centre of the circle and AB be the tangent segment drawn from an external point A touching the circle at B. The tangent at any point of a circle is perpendicular to the radius through the point of contact. ∴ ∠ABO = 90º In right ∆ABO, OA 2 = AB 2 + OB 2 ⇒ OB = OA 2-AB 2 ⇒ OB = 12. 5 2-12 2 ⇒ OB = 156. 25-144 ⇒ OB = 12 ...
