Answer:
1. 28.26cm²
2. 30.96cm²
3. 325in²
Step-by-step explanation:
1. Finding the area of shaded region of using the formula of area of rectangle and area of circle.
Formula :
Solution :
Therefore, the area of triangle is 40.5
Area of circle : A = πr²
Therefore, the area of circle is 28.26cm²
Area of shaded part = (Striangle - Scircle)
Hence, The shaded region is 12.24cm²
2. Finding the area of shaded region of using the formula of area of square and area of circle.
Therefore, the area of square is 40.5m²
Therefore, the area of circle is 113.04m²
Area of shaded part = (Ssquare - Scircle)
Hence, The shaded region is 30.96cm²
3. Finding the area of rectangle of using the area of shaded region.
Area of shade region = (Large - Small)
Hence, The shaded region is 325in²
