Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
![A=\pi \times (11)^2\\\\A=380.13\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%2811%29%5E2%5C%5C%5C%5CA%3D380.13%5C%20cm%5E2)
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
![A=\pi \times (15)^2\\\\A=706.85\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%2815%29%5E2%5C%5C%5C%5CA%3D706.85%5C%20cm%5E2)
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
![A=\pi \times (2)^2\\\\A=12.56\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%282%29%5E2%5C%5C%5C%5CA%3D12.56%5C%20cm%5E2)
Hence, this is the required solution.
The angle missing is at least 90 degrees
Step-by-step explanation:
90 degree - 22 degree = 68 degree
use sin rule
sin90/x = sin68/56
x =60.4 degree
