From a circular card sheet of radius 14 cm, two circles of radius 3.5 cm and a rectangle of length 3 cm and breadth 1cm are removed. (as shown in the adjoining figure). Find the area of the remaining sheet. (Take π =
- Radius of the circular card sheet = 14 cm
- Radius of the two small circle = 3.5 cm
- Length of the rectangle = 3 cm
- Breadth of the rectangle = 1 cm
- The area of remaining sheet.
- =
- =
- =
- =
- =
- = ²
- = ²
- × ×
- × ×
- 1 × 1 ×
∴ Remaining Area = Area of larger Circle
– 2 × Area of Smaller Circle
– Area of Rectangle
- – 3
