Answer:
Step-by-step explanation:
The radius is 7, which helps us find the area of a circle. Divide the area by 2 since it is a semi-circle and you would get 76.969.
Then, you would need to find the area of the square. 14 times 14 is 196.
Add both units, you would get 273 units squared as your final answer.
The answer is C: (3,3)

Answer:
x=−5
Step-by-step explanation:
−3x+5=20
Step 1: Subtract 5 from both sides.
−3x+5−5=20−5
−3x=15
Step 2: Divide both sides by -3.
−3x/-3 = 15/-3
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.
