What is the formula for circumference and volume?

Question

I need to know the formula for finding the circumference of a circle and the volume of a cylinder. I'm studying for my math exam 2moro and for some insane reason, I can't find that info in my txt bk.

Answer 1

2(pi)(r) for the circle and
(pi)(r^2)(h) for the cyliner

Answer 2

Circumference of a circle = 2 x pi x r

Volume of a cylinder = pi x r^2 x h

Where r = radius and h = height

Answer 3

Circumference of a Cirle = 2 x pi x r

Volume of a Cylinder = Area of Base x Height
which is pi x r^2 x h

where
pi = 3.14.... etc
r = radius of circle / base of cylinder
h = height of cylinder

Answer 4

circumference is 2 times pi times radius

volume for a cylinder is 2 times pi times radius times radius times the length of the cylinder. (basically the area of the circle times the length of the cylinder)

Answer 5

PEASE BE UPON YOU,,,
YOUR QUESTION IS "What is the formula for circumference and volume?"

(What is the formula for circumference OF CIRCLE...)

-USING ANGELS (ORDINARY LEVEL MATH)

THE FORMULAE FOR THE CIRCUMFERENCE IS:-

>>> 3.141592654 * DIAMETER <<<

WERE:-

( *) MEANS MULTIPLIED BY
(3.141592654) THE VALUE OF (PI)

BY SYMBOLES >>> PI*D (DIAMETER)<<<
OR >>> 2*PI*R(RADIUS) (HENCE D = 2R)

THE DIAMETER OF THE CIRCLE IS 2 TIEMS THE RADIOUS ( THE DISTANCE FROM THE CENTER OF THE CIRCLE TO THE CIRCUMFERENCE - THE LINE OF THE CIRCLE -

(and volume? OF A cylinder...)

USING ANGELS ORDINARY LEVEL MATH...

VOLUME = PI (3.141592654) * (R*R) * THE HEIGHT

WERE
*= MULTIPLIED BY
PI =3.141592654 (LOOKS LIKE AN ITALIC R)
(R*R) = RADIOUS SQUARED(DONT HAVE IN MY COMPUTER LOOKS LIKE A SMALL "2" LOCATED UPWARD.


>>>>>>>>>>>>SO IN CONCLUTION<<<<<<<<<<<<<<<
CIRCUMFERENCE = 2 * PI * R
OR = PI * D

------------------------------------------
VOLUME OF CYLINDER= PI * (R*R) * H
------------------------------------------

WERE

PI =3.141592654
R=RADIOUS
H=HIEGHT OF THE CYLINDER
D=DIAMETER EQUALS 2R


I WISH I HAD ANSWERED YO IN THE WAY YOU PREFERRED AND LARGNESS IF I MISUNDERSTOOD YOUR QUESTION

Answer 6

for circle

let d=diameter of circle
r=radius of circle
and C =circumference
pi=3.141592654

C=pi*d=2*pi*r

for cylinder

V=volume
r=radius
d=diameter
h=height

V=pi*(d^2/4)*h=pi*r^2*h

i hope that this helps

Answer 7

circumphrence=pi * diameter

volume= (pi*radius^2)length of cylinder

Answer 8

(pi)(r)^2

Answer 9

**** ****** **** is how id describe it
