A storage tank holds 235,500 in3 of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical containers
VMariaS [17]
The volume of every of the 25 cylindrical containers is 235,500/25 = 9,420 in^3

The formula for the volume of a cylinder is:

V = π(r^2).h

Where π=3.14, r = 2.5 in, V = 9,420 in^3, so you can obtain h as:

h = V / (πr^2) = 9,420 / [(3.14) (2.5^2)] = 480 in

Pls help need it ASAP<br> :)

Answer:

x = 4

y = 13

Step-by-step explanation:

x + y = 17

y = 2x + 5

substitute for y:

x + (2x + 5) = 17

reduce:

3x + 5 = 17

subtract 5 from each side:

3x = 12

divide both sides by 3:

x = 4

y = 2(4) + 5

y = 13

The cylinders are similar. the volume of the larger cylinder is 14,464 cubic inches what is the volume of the smaller cylinder
Westkost [7]
We know that

[scale factor]=[measure smaller cylinder]/[measure larger cylinder]
[scale factor]=[9]/[18]---> 1/2

[volume of smaller cylinder]=[scale factor]³*[volume of larger cylinder]
[volume of smaller cylinder]=[1/2]³*[14464]---> (1/8)*14464---> 1808 in³

the answer is
1808 in³
