The area of the 'blue' region (Area 1) is given by the difference. The area in 'blue' may be expressed as the difference between area of sector OBPA and area of triangle AOB.Īrea of triangle = (1/2) r * r * sin(120 degrees) = 50 sqrt(3) / 2 Distance OP = 10 cm so thatĬos(angle BOM) = d(O,M) / OB = 5 / 10 = 1 / 2 Since the two circles have equal radii, M is the midpoint of segment OP. The idea is to find one part (shown in figure below in blue) then multiply it by 2. The overlapping area is made up of two equal parts. Approximate your answer to one decimal place. Find the overlapping area of the two circles. O is the center of C2 and P is the center of C1. Problem The distance between the centers of two circles C1 and C2 is equal to 10 cm. Overlapping circles area problems with detailed solutions. Now, the maximum length of a and b will always be strictly less than the diameter of the circle so all possible values of a and b will lie in the closed interval. Thus, all the combinations of a and b can be checked to form all possible rectangles, and if the diagonal of any such rectangle is less than or equal to the length of the diagonal of the largest rectangle formed (i.e 2 * R, where R is the Radius of the circle as explained above) A window consisting of a rectangle topped by a semicircle is to have an outer. The diameter BD is the maximum diagonal the rectangle can have to be able to be cut from the Circular Sheet. ∴ AD = AB by CPCT(i.e Corresponding Parts on Congruent Triangles) Its easy to see, that ABCD is the largest rectangle that can be formed in the given circle with radius R and centre O, having dimensions a X bĭrop a perpendicular AO such that, ∠AOD = ∠AOB = 90°Ĭonsider the following diagram for further analysis, Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution Check whether triangle is valid or not if sides are given.

Our code will first test which edge of the rectangle is closest to the circle, then see if there is a collision using the Pythagorean Theorem.

We need to get this formula in terms of one variable to create our function: Solve for w: w 2. We can use this information and the Pythagorean theorem (a 2 + b 2 c 2) to get: w2 + h2 4. We know that the diagonal of any inscribed rectangle (blue line) has a length of 2 (because 2 radius diameter).
