Answer 1

Answer:

[tex]112\pi[/tex]

Step-by-step explanation:

hi! for this problem, all we need is the equation for the SA for a cylinder!

here's the equation: [tex]A=2\pi(r)(h)+2(\pi)r^{2}[/tex]

BUT FIRST let's identify our given numbers

the radius, or r, is 4 (r = 4) the height, or h, is 10 (h = 10)

now all we have to do is plug in what is given to the equation above! not so bad, right?

plugged in equation

[tex]A = 2\pi (4)(10) + 2\pi (4)^{2}[/tex]

- now let's simplify!

[tex]2\pi (40) + 2\pi (16)[/tex]

[tex]80\pi + 32\pi[/tex]

[tex]112\pi[/tex]

your answer should be [tex]112\pi[/tex]

A scale model of a bus is 12 inches long. The scale is 1:21. How many inches long is the bus it
represents?

Answers

its 304.8 milimeter

The actual length of the bus that the scale model represents is 252 inches.

To find the actual length of the bus represented by the scale model, you can use the scale ratio.

Given:

Scale model length = 12 inches

Scale ratio = 1:21

Let "x" be the actual length of the bus.

Using the scale ratio:

Scale model length / Actual length = Scale ratio

12 inches / x inches = 1/21

Now, solve for "x":

x = 12 inches / (1/21)

x = 12 inches × 21

x = 252 inches

Therefore, the actual length of the bus that the scale model represents is 252 inches.

Using a set of numbers find the mean round to the nearest tenth median mode and range 8,6,3,7,1,6,5,6

Answers

Answer:

Mean 5.3, Median 6, Mode 6, Range 7

Step-by-step explanation:

First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)

1, 3, 5, 6, 6, 6, 7, 8

Mean: is the average of all the numbers :add all numbers / how many numbers we have

(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)

Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8

(6+6)/2 = 6

Mode: is the number that appears the most so is 6

1, 3, 5, 6, 6, 6, 7, 8

Range: is the difference between the highest and the lowest value

1, 3, 5, 6, 6, 6, 7, 8

8-1 = 7

Answer:

Mean- 42

Median- 6
