1/4 = 0.25
0.25+ 5 + 5.25
120 /5.25
= 22.9 pieces
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.

Answer:
64 degrees
Step-by-step explanation:
The interior angles of a triangle must add up to 180 degrees. So, we can add up the other two, known angles to get 116. Subtract 116 from 180 (180-116) to get 64.
A 3D shape's net is what it looks like after it's flattened out. A net can be folded into a three-dimensional shape. The correct option is C.
<h3>What is the net of a 3-D shape?</h3>
A 3D shape's net is what it looks like after it's flattened out. A net can be folded into a three-dimensional shape. For the same 3D shape, there may be multiple potential networks. You can make a net out of paper and fold it into the desired shape.
The net of the square pyramid has a square and 4 triangles. For a pyramid with a base as a polygon having n sides, the number of triangles is n.
Hence, it can be concluded that a pyramid can contain any number of triangles greater than or equal to 3. Thus, the correct option is C.
