Step-by-step explanation:
5.
and
x/3=-12/5
x=-36/5
The solution is (1,5) because when you plug in your x and y values none of the above answer make sense except (1,5)

Answer:
89.80 cm cubed
Step-by-step explanation:
A hemisphere is essentially just half of a sphere. We want to find its volume.
The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.
Here, the radius is 3.5, so plug this in:
V = (2/3)π * r³
V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed
