dejt4u:Your error The breadth is not the sum of diamter of one big circle and one small circle, It is the sum of one small circle and and unknown value which you have to calculate for. Try it out |

The area of the blue region AB is : AB = (768)[ (7 + 30√2)½ + 2 ] - 1408π ≈ 2511.9783 square unit (4 d.p) Confirm. I can show my working if you want. Cc. ifada123 |

ifada123:Okay. 1) The area of the blue region is the area of the overall rectangle minus the sum of the areas of the circle. The sum of the areas, Ac, of the circle is : Ac = 2[ π(24)²] + π(16)² = 1408π unit² 2) The length of one side of the rectangle is 96 units. The length of the other side is (x + 16) units. x is the size of one of the legs of right triangle whose vertices are: a) The centre of the circle of radius 16 units, b) the mid-point of the upper horizontal side of the overall rectangle, and c) any of the two vertices of the rectangle close to the two big circles. 3) repeatedly using the Pythagorean Theorem, we have. x² + 48² = (40 + 24√2)² x² = (40 + 24√2)² - 48² = 448 + 1920√2 x = (448 + 1920√2)1/2 x = 8(7 + 30√2)1/2 4) The area of the overall rectangle AR is : AR = 96 × (x + 16) = 768[ (7 + 30√2)1/2 + 2 ] 5) Area of the blue portion AB is given by AR - Ac AB = 768[ (7 + 30√2)1/2 + 2 ] - 1408π ≈ 2511.9783 unit² Cc. Ifada123, I am yet to see an error in my working. If you can see any, spot it out. |
