There are 2 formula to find the circumference of a circle.

\huge{\boxed{\bf{Circumference=2\pi r}}}

\huge{\boxed{\bf{Circumference=\pi D}}}

\pi is approximately 3.14
r is radius
D is diameter

and just a side note, \huge{\boxed{\bf{2 r = D}}}
Hope that formula helps you :)

Answer:

2rPi:

Step-by-step explanation:

You can multiply the radius by 2, which gives you the diameter. Then you multiply by Pi, which is 3.14 OR 22/7. If you are in Khan Academy, don't use 22/7.

EASY PLZ HELP!<br> Solve for x. (Show your work)<br> 2x + 3 &gt; 5

<u><em>Hi there! </em></u>

<u><em>Answer:</em></u>

<u><em>X>1</em></u>

<u><em>*The answer must have a positive sign and greater than symbol.*</em></u>

Step-by-step explanation:

First, you subtract by 3 from both sides of an equation.

2x+3-3>5-3

Then, you subtract by the numbers from left to right.

5-3=2

2x>2

You can also divide by 2 from both sides of an equation.

\frac{2x}{2}>\frac{2}{2}

Finally, you divide by the numbers from left to right.

2/2=1

<em><u>Final answer is x>1</u></em>

I hope this helps you!

Have a nice day! :)

:D

Thank you so much! :)

QUESTION 3 Toyota provides an option of a sunroof and side airbag package for its Corolla model. This package costs $1400. Assum
Orlov [11]

Answer:

n=601

Step-by-step explanation:

Formula used:

n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}

Solution:

n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}

Where,

\frac{\alpha }{2}=0.025

As there is no previous estimate for p

Then, p=0.5

Here on using the table

z(\frac{\alpha }{2}) =1.959963985

Also,

E=0.04

p=0.5

Thus,

n=600.2279407

On approximating the value,

n=601

Find the value of x <br> help
Temka [501]

Answer:

6.7

Step-by-step explanation:

This is trigonometry. We will have to find the opposite leg and the hypotenuse is given to us as 10. So we will have to use sin.

Soh in Soh cah toa

                  So  sin(42)=x/10

                        10 times sin(42)=x

                             Evaluate using a calculator=6.69130606 and so on

                                 Rounded to the nearest tenth is 6.7

So the answer is 6.7
