A graphing calculator is recommended. A grain silo consists of a cylindrical main section and a hemispherical roof. If the total
eimsori [14]

Answer:

11.28 ft

Step-by-step explanation:

The volume of a cylinder can be written as;

Volume V1 = πr^2 h

The volume of an hemisphere can be written as;

Volume V2 = (2/3)πr^3

The total volume of the silo is;

V = V1 + V2

V = πr^2 h + (2/3)πr^3

Given;

Volume of silo V= 15000 ft^3

Height of cylinder part h = 30 ft

Substituting the values;

V = πr^2 h + (2/3)πr^3

15000 = 30πr^2 + (2/3)πr^3

15000/π = 30r^2 + (2/3)r^3

2r^3 + 90r^2 - (15000×3/π) = 0

Solving the equation, we have;

r = 11.28 ft or -15.61 ft or -40.67 ft

Since the radius cannot be negative;

Radius r = 11.28 ft

A pyramid with a square base is cut by a plane that is parallel to its base and is 2 units from the base. The surface area of th
icang [17]

Answer:

  6.83 units

Step-by-step explanation:

Let the height of the original pyramid be represented by h. Then the cut off top has a height of (h -2). The scale factor for the area is the square of the scale factor for height, so we have ...

  (height ratio)^2 = 1/2

  ((h -2)/h)^2 = 1/2

  (h -2)√2 = h . . . . . . square root; multiply by h√2

  h(√2 -1) = 2√2 . . . . add 2√2 -h

  h = (2√2)/(√2 -1) ≈ 6.8284 . . . units

The altitude of the original pyramid is about 6.83 units.

Write two expressions to show a number increased by 11. Then, draw models to prove that both expressions represent the same thin
ioda

Answer:

n + 11 and 11 + n

Step-by-step explanation:

Let n be the unknown number,

n is increased by 11,

That is, n + 11

By the commutative property of addition,

The expression would be,

11 + n

For drawing a model that shows n + 11

Take two boxes in which first shows n and second shows 11 and add them,

Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.
