The volume of a cylinder is

V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:

V=40(3.14)(10^2)

V=12560 ft^3

2. Find an equation for the line with slope = 0 that passes through the point (-5, 7).

mel-nik [20]

Answer:

2. y = 7

3. x = 4

Step-by-step explanation:

Slope 0 is when the line is horizontal.. has a constant coordinate

(-5,7) lies on the line so the x-coordinate is 7

Equation: y = 7

A vertical line has all same x-coordinates.

Since (4,-2) is on the line, every point had x-coordinate of 4.

Equation: x = 5

1. The prism below measures 6 inches x 3 inches x 10 inches. A diagonal

12345 [234]

9514 1404 393

Answer:

√145 ≈ 12.04

Step-by-step explanation:

The length of the space diagonal is the root of the sum of the squares of the prism edge lengths:

d² = a² +b² +c² = 6² +3² +10² = 145

d = √145 ≈ 12.04 . . . inches

The face diagonal is found using the Pythagorean theorem in the usual way:

f² = a² + b²

The space diagonal is the hypotenuse of the right triangle whose sides are the face diagonal and the remaining edge:

d² = f² +c²

d² = a² +b² +c²

Here is a diagram.

The price of the product decreased by 10%and then decreased by 20% . calculate total percentage change between the final and ini

aev [14]

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price $V_{1}$ (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price $V_{2}$ which is 72.
