Answer:
16
Step-by-step explanation:
To start off this problem, we are given that the line AB is equal to the line CD. In addition to that, we are given that the line EF equally intersects line AB and line CD. This provides us proof that angle AGH is equivalent to angle DHG. From this information, we can solve this problem relatively easily.
Lets work with this equation:
Next, divide 80 by 5.
This means that x is equal to 16.
Answer:
C
Step-by-step explanation:
Since the circle is inscribed inside of the square, its diameter is the same as the side length of the square, or 8. This means that the radius is 8/2=4. The formula for the volume of a circle is , or in this case
. The area of the square is 8*8=64 square feet. 50.24/64 is equal to 78.5%, or answer choice C. Hope this helps!
