Volume? Correct answers please

Answers

Answer:

V = 1385.44

Step-by-step explanation:

The equation for volume is V = π r 2 h! Where V = volume, r = radius (half the diameter), and h = height. Now lets substitute what we know into this equation!

Since we are giving the diameter (14) we must divide by 2 to find the radius.

                         14 ÷ 2 = 7

Radius = 7

Height = 9

V = ?

Time to plug these values in!

V = π [tex]7^{2}[/tex] (9)

We have to distribute pi to 7 square that term and then multiply the value by 9.

V = 1385.44

Hope this Helps! :)

Find the volume of the rectangular prisim 6cm 4cm 12cm

Answers

Answer:

288cm²

Step-by-step explanation:

The volume of a rectangular prism can be easily calculated by multiplying the height by the width by the length

Assuming that the lengths given ( 6cm, 4cm and 12cm )  are the width, height and length

If so then the volume is equal to 6 * 4 * 12

6 * 4 = 24

24 * 12 = 288

volume = 288cm²

Answer:

The answer is 288

The equation of the function is Y=4x+5.Find the value of y when
x=3
x=-2

Answers

Question:-

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

Answer:-

Given:-

y = 4x + 5 [Equation]

To Find:-

The value of y when x = 3 , x = -2

Solution:-

y = 4x + 5 [Given equation]

[tex] \therefore [/tex] When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

y = 17 [Answer]

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

y = -3 [Answer]

Last year, a lighting supplier called Bright Idea shipped a total of 37,220 lamps to its distributors. This year, the supplier shipped 29,776 lamps. What is the percent of decrease in the number of lamps shipped annually?

Answers

Answer:

25%

Step-by-step explanation:

Given data

Last years shipment= 37220  lamps

These years shipment= 29776 lamps

% Decrease= Initial-Final/Initial*100

% Decrease= 37220-29776/29776*100

% Decrease= 7444/29776*100

% Decrease= 0.25*100

% Decrease= 25%

Hence the decrease is 25%


How much larger is 6 x 10^5 compared to
2 x 10^3?Explain how you know.

Answers

Answer:

6 x 10^5 is 300 times greater than 2 x 10^3.

Step-by-step explanation:

Use division to compare.

(6 × 10^5)/(2 × 10^3) = 6/2 × 10^5/10^3 = 3 × 10^2 = 3 × 100 = 300

6 x 10^5 is 300 times greater than 2 x 10^3.

There is 6 × 10⁵ is 300 times greater than 2 × 10³.

What is the Scientific Notation?

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

The exponents are given in the question, as follows:

6 × 10⁵ and 2 × 10³

The exponents in scientific notation as a shorthand for the number of zeroes in the number.

We use division to compare.

( 6 × 10⁵)/(2 × 10³)

= 6/2 × 10⁵/10³

= 3 × 10²

= 3 × 100

= 300

This means 6 × 10⁵ is 300 times greater than 2 × 10³
