Answer these two questions pls (ill give u brainly)

Answer:

1a)81 b)54 c)27 d)0

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

The total is 27, as it should be.

The area of the base of the part holding water is ...

  π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

  V = Bh

  V = (2100π cm²)h = 200·1000 cm³

  h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.
