A cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet. how much water can the silo hold, in terms of π? ref

Anestetic [448]

The amount of water that the cylindrical shaped silo can hold is 324π ft³.

Given the data in the question;

Diameter of the cylindrical silo; $D = 18ft$

Radius; $r = \frac{D}{2} = \frac{18ft}{2} = 9ft$

Height of the silo; $h = 4ft$

Volume of the silo in terns of $\pi$ ; $V = \ ?$

<h3> Volume</h3>

The volume of a cylinder simply signfies the amount of space in, i.e the quanity of materials it can carry or hold.

The volume of a cylinder is expressed as;

$V = \pi r^2h$

To determine the amount of water the silo can hold, we substitute our given values into the expression above.

$V = \pi r^2h\\\\V = \pi * (9ft)^2 * 4ft\\\\V = \pi * 324ft^2\\\\V = 324\pi ft^2$

Option B) 324π ft³ is the correct answer.

Hence, the amount of water that the cylindrical shaped silo can hold is 324π ft³.

What is the difference between GPA and cumulative GPA?

ioda

Answer:

The difference is that the cumulative GPA covers shorter periods, like a term or a semester. The overall GPA refers to the average grades obtained by a student throughout his entire academic experience. This means the overall GPA includes grades from all terms and semesters.

Two small metal cubes with masses 2. 0 g and 4. 0 g are tied together by a 5. 0-cm-long massless string and are at rest on a fri

Aleks04 [339]

The energy of the system, tension in the string, and speed of each cube are respectively; U = 0.72 J, T = 14 N and (V₂, V₄) = (-22, 14)

<h3>Calculation of energy and tension in a String</h3>

We are given;

Mass of cube 1; m₁ = 2 g

Mass of cube 2; m₂ = 4 g

Distance between cubes; d = 5 cm = 0.05 m

Charges of cubes; Q = q = +2. 0 μc = 2.0 × 10⁻⁶ C

A) Formula for the energy of the system is;

U = kQq/d

U = 8.99 × 10⁹ × (2.0 × 10⁻⁶ C)²/0.05 m

U = 0.03596/0.05

U = 0.72 J

B) Formula for the Tension is;

T = U/d

T = 0.72/0.05

T ≈ 14 N

C) Momentum is conserved, and as such the initial momentum is zero. Thus;

0 = (0.0020 × V₂) + (0.0040 × V₄)

⇒ V₂ = -2V₄

Energy is also conserved and so;

(½ × 0.0020 × (-2V₄)²) + (½ × 0.004 × (V₄)²) = 0.72 J

-0.0040V₄² + 0.002V₄² = 0.72 J

0.0060V₄² = 0.72 J

V₄² = 0.72/0.0060

V₄² = 120

V₄ = √120

V₄ ≈ 11 m/s

Recall that; V₂ = -2V₄

Thus;

V₂ = -2(11) m/s

V₂ = -22 m/s

Thus;

(V₂, V₄) = (-22, 14)
