Question

Find volume of the cylinder and the amount of sheet metal that would be needed to make this tank with the given dimensions: figure in comments.

Answer 1

Do you know what "Amount of Sheet Metal" refers to?

Answer 2

The formula for finding the volume of a cylinder is
V = pi r^2 h

Answer 3

its pie m^2

Answer 4

i got 637 pie

Answer 5

To find the amount of required sheet metal, use the formula for cylinder surface area here:

Answer 6

I got 362.9 for the surface area

Answer 7

HELP?

Answer 8

The Volume of this cylinder is 500.045

Answer 9

Its multiple choice both questions.

Answer 10

the closet answer i have is 490 pie

Answer 11

oh in terms of pie. do you have 159.25 pi?

Answer 12

yes!

Answer 13

And the second question is in pie too.

Answer 14

and what is up with the sheet metal are we looking for Surface Area?

Answer 15

were trying to find the amount of sheet metal it would take to make the cylinder with the numbers given in the equation

Answer 16

115.5pi

Answer 17

Got it! I have a few more questions if you dont mind?

Answer 18

Sure. I just took a test on Volume and SA last friday in my Geometry class.

Answer 19

what the surface area of wood used to make the jewlery box?

Answer 20

And calculate the volume of it too.

Answer 21

The base is 20 inches squared

Answer 22

okay thanks. the Area of the base is 20 in squared. I was going to divide that into a trapezoid to get the area of the base.

Answer 23

112.8 in squared

Answer 24

Volume is 300 cubic inches.

Answer 25

I dont have 112.8 for the SA

Answer 26

I have 146, 300, 292, and 272 pie

Answer 27

292!

Answer 28

okay thank you

Answer 29

Yep, just remember the formulas. For prisms Volume is B(area of base)h
V=Bh
