Area of circle = pi × radius²
For qns 4, rearrange the quadrant, and you'll get the same figure as qns 6.
The radius in qns 4 is 14 ÷ 2 = 7
The radius in qns 5 is equal to the side of square
The diameter of the circle in 6 is 20cm, diameter = 2 × radius
So just use pi × radius × radius to get the area of your circle
As example, qns 4, 22÷7 × 7 × 7 = the area of the circle, then just, the area of the square minus the circle and you'll have your shaded area.
