The answer for this problem would be 628.3 Cubic Meters.

To solve, simply follow the way of finding the volume of a cylinder.

Calculate volume of a cylinder: V = πr2h.

Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh.

Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr. ...

Total surface area of a closed cylinder is:

628.3

Hope this helps:}

diamong [38]

Answer:

The answer to your question is:

Step-by-step explanation:

Data

f(x) = -2x² + 8x - 2

Process

                -2x² + 8x = y + 2

                -2(x² - 4x + 4) = y + 2 - 8

                -2(x - 2)² = y - 6

                    (x - 2)² = 1/2 (y - 6)

Vertex = (2, 6)

Axis of symmetry =   x = 2

y-intercept

                 f(0) = -2(0)² + 8(0) - 2

                 f(0) = 0 + 0 - 2

                 f(0) = -2

Domain    (-∞, ∞)

Range    (-∞, 6]

A nut store normally sells cashews for​ $4.00 per pound and peanuts for​ $1.50 per pound. But at the end of the month the peanut
Dvinal [7]

Answer: 40 pounds of cashews should be mixed with the peanuts to ensure no change in the​ revenue

Step-by-step explanation:

Let x represent the number of pounds of cashews that should be mixed with the peanuts to ensure no change in the​ revenue.

The nut store normally sells cashews for​ $4.00 per pound and peanuts for​ $1.50 per pound.

In order to sell 60 pounds of​ peanuts, the manager decided to mix the 60 pounds of peanuts with some cashews and sell the mixture for $2.50 per pound. It means that

4x + (1.5 × 60) = 2.5(60 + x)

4x + 90 = 150 + 2.5x

4x - 2.5x = 150 - 90

1.5x = 60

x = 60/1.5

x = 40
