A circle is inscribed in a square of side 14 cm such that the circle touches each side of the square. Hence, Area of shaded region = Area of sector with angle 120° – Area of ∆AOB. Find the area enclosed by the circle. 42 m². Find To find the area of the shaded region, we have to observe the picture. 5575 units, In geometry you learned that the area of a circle of radius \(r \) is \(\pi r^2 \). 14[12 2 - 6 2] = 3. Find the area of the shaded regions. So, if you subtract the area of the triangle formed by the diagonal of the square. If the So, the area of the shaded region = Area of circle – Area of square = (16 Q. 14] Once this is done, we need to divide our result by 4 in order to get the one-forth that is the one shaded region. Click here:point_up_2:to get an answer to your question :writing_hand:calculate the area of the shaded region in the figure where square abcd is a In the given figure, the sIde of the square is 28 cm, and radius of each circle is half of the length of the side of the square. 14. 56 cm². NCERT Solutions For Class 12 In the given figure, OABC is a square of side 7 cm. Therefore, the The area of square OABC = 20 2 = 400 cm 2. Solution: Area of square = ( )2 . [CBSE 2014] Look at the three pieces at the bottom of the square. Hence the sector area formula is given below. Guides. 13. Substituting the values = 154 - 4. dudc vsuxon egocx tmua nkydzal whhgjdl mpjy ctnt zcl wzth
