The answer is 108cm^2 because it gives you the entire height of the shape minus the height of the rectangle the divide it by two to find the height of the triangles the find the area of all the different shapes then add it together

Answer: 7.29π mm²
Step-by-step explanation:
First, I am assuming XY is the diameter of the circle :)
The formula for the area of a circle is πr² (r = radius)
So that means we need to divide the diameter by 2 to find the radius
5.4 / 2 = 2.7
Now we simply plug in our numbers!
3.14 · 2.7²
3.14 · 7.29
And that's it!
Hope this helped you :)
 
        
             
        
        
        
If it is less than full it means it is anything below 5/5 or 6/6, so they both have less than full water bottles...
If you meant less than half full, Josan has 0.5/5 less than half, so yes, They should stop in this case as well.
