COMMON TANGENTS TO THE CIRCLES Let S1 = 0 and S2 = 0 be two circles with radii r1 and r2 and d, the distance between their centres.1. When r1 - r2 > d, there is no common tangent. Here one circle is completely within the other.2. When r1 - r2 = d, there is one common tangent. Here circles touch each other internally.3 If the circles are tangent, then they will have three common tangents, but this can be understood as a degenerate case: as if the two tangents coincided. Moreover, the algorithm described below will work in the case when one or both circles have zero radius: in this case there will be, respectively, two or one common tangent

The shaded region below is the common area to four semicircles whose diameters are the sides of the square with side length 4x Two circles of radii 4 cm and 9 cm respectively touch each other externally at a point and a common tangent touches them at the points P and Q respectively. Then the area of a square with one side PQ is where r1,r2 are the two radii and s1,s2 are the two square sides. This is easily seen by looking at each square individually and noticing that the distance d1 from the circle/square center to the square corner is sqrt(2) * r, and the desired distance within that square is d1 - the circle radius r Chapter 14.

Thus we can prove (12) by using Corollary 3. Remark 2. The relation (12) for the radii of four circles in FIGURE 9 is proven also by Michiwaki et al ([5], Theorem 2). In FIGURES 13 through 18, the following relation holds for the radii a, b, c, and The radii of the two nodes (circles) are r1 and r2, respectively, with r2 < r1. A triangle for each node can be constructed. One side is the radius of the node (i.e. the radius of detection). Another side is a normal from the center of the circle to the chord of detection. This line segment will bisect the chord, by definition

Formula for length of the tangents of circles: Here Two circles origins O & O' and radius are r1 and r2 respectively. Direct common tangent AB & transverse common tangent = CD. Length of direct common tangent AB = √ [ (Distance between two. 5 A region in the circle, bounded by an arc and a chord, including the arc and the chord is If a copper wire of length 88 cm is bent in the form of a circle, then the radius of the circle is : If the sum of the circumferences of two circles with radii R1 and R2 is equal to the circumference of a circle of radius R, then : (a) R1 + R2. Given two chords of a circle AB and CD intersect at point X, with . arc AD = 110 and arc BC = 85, find the measure of . Find the length of a common internal tangent segment of 2 circles . with radii 4 and 12, whose centers are 20 units apart. A circle with radius r and a square with perimeter p have equal areas. Find the value of . A) B. The long chord of a compound curve is equal to 250m. The PC of the curve is at STA 10+000 and the P.C.C. is at station 10+139.393. The angle that the chord connecting the P.C. and P.C.C, makes with the tangent passing through P.C. is equal to 40. Assuming the common tangent is parallel to the long chord. Determine th

There are two concentric circles with radii 12 cm and 15

Area of Circle 2/Area of Circle 1 = 314.1/3.141 = 100 times = 10^2. This suggests that if we multiply the radios by 20 times, the increase in area will be the square of the factor the radius is increased which in this case is 20^2 = 400 times greater area Find the length of a chord which is at a distance of 4 cm from the centre of a circle of radius 5 cm. the perpendicular drawn from the centre of a circle to a chord divides the chord into two equal parts. ∴ AP = x AB => AB = 2AP => AB = 2 x 3 = 6cm Let the heights of cylinders are h1,h2 and radii r1, r2. Hence, required ratio of.
