WebLet us try using the formulas mentioned above in a practical illustration to find the diameter. Observe the example ... i.e., Radius = Diameter/2. The diameter of a circle is a line segment that passes through the center of a circle and has two endpoints at the circumference. It is twice the length of the radius of a circle, i.e., Diameter = 2 ... WebNov 8, 2024 · We are given that BD=5 thus to find AC we need to know the length of any other line segment. Also in such kind of triangles might be useful to equate the areas to …

WebThe circle x 2 + y 2 = 1 cuts the x-axis at P and Q. Another circle with centre at Q and variable radius intersects the first circle at R above the x-axis and the line segment PQ at S. If A is the maximum area of the triangle QSR then 3 √ 3 A is equal to _____ . WebAnswer (1 of 6): Since AB is the diameter of the circle, it is the hypotenuse of the right triangles ACB & ADB thus formed on both sides of it.

Answered: In circle D, segment AB is a diameter. bartleby
WebJun 7, 2024 · Input: r = 4 Output: 8 Input: r = 9 Output: 18. Proof that the Longest chord of a circle is its Diameter: Draw circle O and any chord AB on it. From one endpoint of the chord, say A, draw a line segment through the centre. That is, draw a diameter. Now draw a radius from centre O to B. By the triangle inequality, AB < AO + OB = r + r = 2r = d. WebJan 13, 2024 · Firstly it primarily has to do with the fact that vertices of each triangle is formed at the ends of the diameter of the circle they are inscribed within. Since the line AB intersects the circle (and its diameter) it is sufficient to say that these angles are similar within the triangles as well. WebSep 28, 2024 · 19. hannahwithnell.
