Question

does 2thesymbolforpieR mean 2 times pie times r

Answer 1

The symbol for pi is just this π
It means 3.14159265 that is all - no 2 multiplied in there.

Answer 2

I don't know why you typed 2thesymbolforpieR
Anyway, pi is just π

Answer 3

Maybe you were trying to type something like this?
2 PI r
which is 2 times pi times the radius of the circle which equals the circumference.

Answer 4

I understand although the question says find the area of a circle with a given diameter of 12.56. my computer doesnt have a pie symbol.

Answer 5

so it will be 2 times pie times 12.56?

Answer 6

no because cirumfeence = PI * diamter

Answer 7

and the question is in diameters.

Answer 8

well circumference is strictly pi*diameter

Answer 9

by the way to make the pi symbol hold down the alt key and at the same time type 227 and you will get π

Answer 10

I'm not trying to find circumference, I'm trying to find the area. Please explain?

Answer 11

Can you make the pi symbol yet? π
Anyway circle area = π • r²

Answer 12

I tried it, it's not working

Answer 13

You know the question and the area?

Answer 14

or did you mean the π symbol

Answer 15

I meant the pie symbol.

Answer 16

Did you use the keypad on the right side of the keyboard?
If you use the numbers at the top of the keyboard, it won't work.

Answer 17

▬0♠♣♦☻☺◘○I'm trying to find the area in diameters.

Answer 18

←π

Answer 19

yahoo I got it!!!!

Answer 20

now back to the question

Answer 21

You don't find the area in diameters.
Anyway, diameter = 12.56 so radius =
12.56 / 2 =
6.28
Area would then equal 3.14159 * 6.28 * 6.28

Answer 22

I'm sry ur dividing, daaaaaaaaaaaaa

Answer 23

why do u multiply it by pie twice

Answer 24

I am not multiplying it by anything
diameter = 12.56
radius = one half diameter = 12.56 / 2 = 6.28
area of a circle is π•r²
so area = π • 6.28 • 6.28
= 123.9

Answer 25

;thanks Im gonna have to make flash cards.

Answer 26

okay - glad to help you out
you'll find circle area is easy as π

Answer 27

funny

Answer 28

thanks :-)

Answer 29

Why does my book have c=2πr? Is it a given that pie always stays pie?

Answer 30

to find the area, I take πr to the second power?

Answer 31

I got 6590, well actually 6589.930414.

Answer 32

circumference = 2 • π • r
area = π • r²

Answer 33

You do not tkae π•r to the second power
only 'r' to the second power

Answer 34

π • r to the second power is
π •π • r • r
but that is NOT how circle area is calculated
It is calculated by
π • r • r

Answer 35

Well I came back here. I hope you note what I posted.

Answer 36

I did π * 6.28 * 6.28=123.9 ft.?

Answer 37

Yes that's what it equals.
Actually it would be 123.9 square feet
