Answer:
64.84 square cm
Step-by-step explanation:
two semicircles/a circle with 6cm diameter = 28.27 cm squared
two semicircles/a circle with 4cm diameter = 12.57 cm squared
28.27 + 12.57 + 24 = 64.84
Answer:
Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ.
Step-by-step explanation:
Start with a line segment PQ that we will copy. Mark a point R that will be one endpoint of the new line segment. Set the compasses' point on the point P of the line segment to be copied. Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ.

Answer:
The size of a television screen is ![48\ in](https://tex.z-dn.net/?f=48%5C%20in)
Step-by-step explanation:
Let
x-----> the length of the diagonal of the screen
we know that
Applying the Pythagoras Theorem
![x^{2}=H^{2}+W^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%3DH%5E%7B2%7D%2BW%5E%7B2%7D)
we have
![H=38.4\ in](https://tex.z-dn.net/?f=H%3D38.4%5C%20in)
![W=28.8\ in](https://tex.z-dn.net/?f=W%3D28.8%5C%20in)
substitute the values
![x^{2}=38.4^{2}+28.8^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D38.4%5E%7B2%7D%2B28.8%5E%7B2%7D)
![x^{2}=2,304](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D2%2C304)
![x=48\ in](https://tex.z-dn.net/?f=x%3D48%5C%20in)
