Answer:
The volume of the solid will be = 134.1 cubic units.
Step-by-step explanation:
The base of a solid has the equation of a circle x² + y² = 16 in the xy-plane. Cross-sections perpendicular to the y-axis of the solid are semicircles.
Therefore, the solid will be the shape of a hemisphere.
Now, the radius of the hemisphere will be 4 units.
{Since the base of the hemisphere is on the xy-plane and have equation
x² + y² = 4²}
Therefore, the volume of the solid will be =
cubic units. (Answer)
Answer:
I hope this helps you
Step-by-step explanation:
The answer is 4
|x|>-2 should be your answer
|x| means that no matter what the number (x) is, it will always be positive.
Because a positive number is always greater than a negative, (A) is your best answer choice
