Question

volume of a cylinder is1131.0 cubic centimeters. the lengh of the cylinder is 40 centimeters. what is the radius of the cylinder

Answer 1

pi r^2 (40) = 1131
r =sqrt (1131/(40pi))

Answer 2

i dont get it

Answer 3

helloooooooooooooooooooo

Answer 4

hello are you still there

Answer 5

volume of cylinder is pi* r^2*h

Answer 6

V=1131.0, h=40 solve for r

Answer 7

what does ^ mean

Answer 8

it means to the power of

Answer 9

how do i solve for r

Answer 10

okay thanx

Answer 11

use the equation to solve for r: you have V=pi*r^2*h were h=40 and V=1131

Answer 12

1131=pi*r^2*40

Answer 13

i like mtininaya better please help me

Answer 14

so since we want to solve for r, we need to divide both sides by 40 and pi

Answer 15

1131/(pi*40)=r^2

Answer 16

take the square root of both sides to get r

Answer 17

im confused sorry can u go step by step

Answer 18

click on that up there

Answer 19

hows that?

Answer 20

I divided both sides by h and pi to get r^2 by itself. i took square root of boths to get r. and then volume=V=1131 and height=h=40 and radius=r

Answer 21

is it 1 centimeter

Answer 22

is it 1 centimeter

Answer 23

did you look at the attachment?

Answer 24

the radius is sqrt(1131/[40pi])

Answer 25

so to divide 1131/40pi i first mulyiply 40 times 3.14 right?

Answer 26

If you do that, you will get an approximation. I would stop where I stoped

Answer 27

bt i dnt get what the answer is because in my paper is multipal choice. a.1 centimeter b.2 centimeter c.3centimeter d.centimeter

Answer 28

ok so they rounded it?

Answer 29

i get 3 centimeters then

Answer 30

can u show me how u got everything in the attach file

Answer 31

what kindof calculator do you have?

Answer 32

ti83?

Answer 33

the one in the computer

Answer 34

ok so type 40

Answer 35

40

Answer 36

hit the multplication sign

Answer 37

type 3.14

Answer 38

hit the equal

Answer 39

remember 125.6

Answer 40

now do 1131 and hit the division sign then type in 125.6

Answer 41

then last step hit the square root sign
