775.734624395
Use calculator
\text{Volume of Hemisphere HALF of Volume of Sphere:}
Volume of Hemisphere HALF of Volume of Sphere:
\frac{775.734624395}{2}
2
775.734624395
Divide volume by 2
387.867312198
387.867312198
\approx 387.9\text{ m}^3
≈387.9 m

Step-by-step explanation:
Got 100% on Plato
Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation
Answer:
see below
Step-by-step explanation:
Closed under addition, subtraction and multiplication
Not closed under division :-
for example 3/4 = 0.75 which is not an integer
