how do you find the circumference

OpenStudy (ragingsquirrel):

of a circle?

OpenStudy (anonymous):

yes

OpenStudy (ragingsquirrel):

multiply the diameter by Pi. (3.14)

OpenStudy (anonymous):

you think i tryed

OpenStudy (ragingsquirrel):

so do you know the diameter or the radius?

OpenStudy (anonymous):

like it says 15 cm so i times by pi (3.14) right

OpenStudy (aravindg):

2*pi*r

OpenStudy (ragingsquirrel):

you had to post that 4 times...

OpenStudy (anonymous):

circumferrence of a circle =2*3.14*r where r is the radius of the circle

OpenStudy (anonymous):

i ask a yes or no ?

OpenStudy (anonymous):

yes

OpenStudy (ragingsquirrel):

Oops i mean diameter.

OpenStudy (ragingsquirrel):

But yes. Just multiply 15 by 3.14.

OpenStudy (anonymous):

thankss talk latter

OpenStudy (ragingsquirrel):

OpenStudy (amistre64):

2r = d 2pi r = pi d

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

$2\pi*r$

OpenStudy (ragingsquirrel):

;)

OpenStudy (anonymous):

P (circunference)=2pi*r
