A cylinder has 18 inch diameter and is 15 inches tall it is filled to the top with water a 6 inch diameter ball is in place with
k0ka [10]

Answer: 1,179\pi\ in^3

Step-by-step explanation:

The volume of a cylinder can be calculated with the following formula:

V=\pi r^2h

Where "r" is the radius and "h" is the height.

The volume of a sphere can be found with this formula:

V=\frac{4}{3}\pi  r^3

Where "r" is the radius.

Then, volume of the empty cylinder is:

V_c=\pi (\frac{18\ in}{2})^2(15\ in)\\\\V_c=1,215\pi \ in^3

And the volume of the ball is:

V_b=\frac{4}{3}\pi  (\frac{6\ in}{2})^3\\\\V_b=36\pi \ in^3

 Finally, you need to subtract them in order to calculate how much water is in the cylinder:

1,215\pi \ in^3-36\pi \ in^3=1,179\pi\ in^3

Is (0,0) a solution to this system ?
Akimi4 [234]
The answer is choice B

The point (0,0) makes the first inequality true since
y >= x^2-4
0 >= 0^2-4
0 >= 0
is true

However, the point (0,0) does not make the second inequality true
y < 2x - 1
0 < 2(0) - 1
0 < -1
because 0 is not smaller than -1
