Question

A cylindrical thermos has a radius of 2 in, What is the volume of similar thermos with a radius of 3 in. hold ( please explain)

Answer 1

The formula for a cylinder's volume is pi (3.14) times radius^2 times the height.

So, first find the volume of the first thermos.
If the diameter is 2(1/2) in, the radius is half of that, or 1(1/4)in.
V= 3.14 x (1.14in)^2 x 9, where V is the volume. Use a calculator to solve this.

Then take your answer, which is the volume of the container, and divide it by the radius of the 2nd travel mug.
If the diameter is 3 (1/2) in, then the radius will be 1(3/4) in.

So, set up an equation.
answer to the above= 3.14 x 1(3.4)^2 x h

So, solve for h to find your answer.

Answer 2

Cylinder volume = (Pie x diameter^2)/4 x height of the cylinder

so using the 2 1/2 and 9 we get 44.17 in^3 for volume

now solve for height with 31/3 x h = 44.17 in^3 of liquid

Answer 3

im still confused! sorry!!

Answer 4

h = 44.17

Answer 5

what does 2(1/2) mean

Answer 6

it means two and one hafe

Answer 7

but the diameter is only 2

Answer 8

i now it is hard to explan i gave you your answer i would say look over it agean

Answer 9

okay

Answer 10

ok tag me if you tag me if you need me kk ttyl

Answer 11

bye!
