what is the area of a semi circle when the diameter is 6

Answers

Answer: 14.13

Step-by-step explanation:

Your answer is 14.13

First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.

To find the radius, we need to divide the diameter by two, which is 3.

So like

3.14 x 3^2/2

3.14 x 9/2

28.26/2

A=14.13

Answer:

14.13

Step-by-step explanation:

normal circle area equation = r^2*3.14

6/2=3

3*3*3.14

= 28.26

it's a semicircle so /2

=14.13

Tell whether the given statement is true or false. Explain your choice.
7. All real numbers are rational.
8. All whole numbers are integers.

Answers

For number 7 since the rational number is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. So you should choose false

8 yes! All whole numbers are integers. For an example 0 is a whole number, 0 Is ALSO a integer. So you should choose truth
7. False. Since the set of rational numbers is countable, and the set or real numbers is uncountable, almost all real numbers are irrational.
8.true. All whole numbers are integers, so since 0 is a whole number, 0 is also an integer

Find The value of H:

S=2πr(r+h)

Answers

Answer:

[S / (2πr)] - r = h

Step-by-step explanation:

You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.

S = 2πr(r + h)

Divide by 2πr to try to isolate h

S / (2πr) = r + h

Subtract r from both sides to get h by itself

[S / (2πr)] - r = h

That is your final answer.

[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]

[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]

[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]

[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]

Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.

pages---> 4/3=32/3
hours---> 1/4 = x

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages
