Answer» seer the following:11.5.2 Area of CircleAmange the separate pieces as shown in Fig 11.36, which is roughly a parallelogram.A farmer dug a flower BED of radius 7 m at the centre of a FIELD. He needs todiredpurchase fertiliser. If I kg of fertiliser is required for 1 square metre area.how much fertiliser should he purchase?. What will be the cost of polishing a circular table-top of radius 2 m at the rateof 10 per square metre?Can you tell what we NEED to find in such cases, Area or Perimeter? In suchmakes we need to find the area of the circular region. Let us find the area of a circle, usingnaphpaper.Draw a circle of radius 4 CM on a graph paper (Fig 11.34). Find the area by countinghe number of squares enclosed.As the edges are not straight, we get a rough estimate of the area of circle by this method,71 side There is another way of finding the area of a circle.Draw a circle and SHADE one half of the circle [Fig 11.350). Now fold the circle intolerosighths and cut along the folds (Fig 11.35(11)].Fig 11.35Fig 11.34Fig 11.36
