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
Answer:
B.
Step-by-step explanation:
If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.
In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.
In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.
In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.
In Option D, it is the same thing as Option A.
So, your answer is Option B.
Hope this helps!
