Radius of circle inscribed in a rhombus
WebSep 15, 2024 · Find the radius R of the circumscribed circle for the triangle ABC from Example 2.6 in Section 2.2: a = 2, b = 3, and c = 4. Then draw the triangle and the circle. Solution: In Example 2.6 we found A = 28.9 ∘, so 2R = a sinA = 2 sin28.9 ∘ = 4.14, so R = 2.07. WebNov 14, 2024 · Here are the steps I took, In details. 1) First I calculate the Area of the circle through radius, which is A = 16π. 2) Then I calculate the area of the square through this method: " A square is also a rhombus (with equal diagonals), so we can use the formula for the area of the rhombus. What do we use as the value of the diagonal?

WebSep 25, 2024 · Approach: From the figure, we see, the radius of inscribed circle is also a height h=OH of the right triangle AOB. To find it, we use equations for triangle’s area : Area AOB = 1/2 * (a/2) * (b/2) = ab/8 = 12ch where c = AB i.e. a hypotenuse. So, r = h = ab/4c = ab/4√ (a^2/4 + b^2/4) = ab/2√ (a^2+b^2) and therefore area of the circle is

WebAug 18, 2013 · A rhombus is a flexible shape which can range from almost a square to a very narrow shape. A rhombus with sides of x cm can contain a circle with any radius less than x/2 cm. The information in the question is insufficient to determine the radius. And a ratio requires some characteristic of the inscribed circle to be compared to an analogous … WebWhat is the radius of a circle inscribed in a rhombus with diagonals of length and ? Solution. Let and be the lengths of the diagonals, the side, and the radius of the inscribed circle. Using Pythagorean theorem we can compute . We can now express the area of the rhombus in two different ways: as , and as . Solving for we get .
WebThe Rhombus and the inscribed circle can be shown according to the following figure: ABCD is the rhombus, with diagonals 16 cm and 12 cm in length. The circle has the center at O, and the radius is r. So, we get: AO = OC = 16/2 = 8 cm And DO = OB = 12/2 = 6 cm Applying Pythagoras theorem to the ΔADO, we get: (AD) 2 = (AO) 2 + (OD) 2
