Answer:
x = 0.5
Step-by-step explanation:
2.2X + 2.2 = 1.1
subtract both sides by 2.2
2.2X = -1.1
divide both sides by 2.2
we get x = 0.5 or 1/2
Answer:

Step-by-step explanation:
Find the volume of the sphere first :
V sphere = 
π 6^3 = 902.51
Then use the volume of the sphere to find the height :
Formula = V/π
902.51/π(6)^2 = 8.004 (rounded is 8)
hope this helped :)

The expression that represent the area of the cut off part is 81π / 4
<h3>How to find area?</h3>
The area of the cut off part can be found as follows:
Area of a circle = πr²
where
Therefore, the cut off part is like 1 / 4th of a circle.
Hence,
area of the cut off region = πr² / 4
r = 9 inches
area of the cut off region = π9² / 4
area of the cut off region = 81π / 4
