How would one put 70 cubic feet into perspective?
-- the space inside a cube (box) that's 4ft 1.5inch on every side -- the space inside a spherical balloon that's 5ft 1.4inch in diameter (across)
How much helium is needed to fill 20 12 inch balloons?
To find the volume of a sphere with a known diameter or radius (which is half the diameter), use the following formula: Asphere = 4/3 pi r3 pi = 3.14 and r = radius For a balloon with a diameter of 12 inches, the radius is 6 inches. Taking that information to the formula, you'll get 25.133 cubic inches (in3).
A balloon has a volume of 6.3 liters Calculate the mass of helium that it would take to fill the balloon?
The mass of helium contained will be 1 gram.
Consider a balloon that is being inflated As the balloon increases in size the area of its surface increases Each time the balloon's diameter doubles what do you expect for the change in the area?
For any geometric figure, surface area is proportional to (linear dimensions)2 .As the balloon's diameter doubles, its area increases by the factor of (2)2 = 4 .
What happens to the shape of a helium balloon as it rises?
As the balloon rises, the air pressure outside will decrease, and the balloon skin will deform till the pressure on both sides of the skin is the same. Thus your balloon will inflate in shape, towards the spherical, which is the limiting shape for a simple balloon.
What is the perimeter of a hot air balloon?
It varies by balloon. If the balloon is spherical, the circumference is pi times the diameter. If you are asking what the skin is made of, it is usually coated, very light fabric.
What is the radius of a 12 inch balloon?
Assuming the balloon is perfectly spherical and that the 12" you state refers to the diameter of the balloon then it is obviously 6". If you can't assume any of the above then your question cannot be answered.
Did the Montgolfier Brothers fly the first hot air balloon?
On June 5, 1783 they used fire to inflate a spherical balloon about 30 feet in diameter that traveled about a mile and one half before it came back to earth.
How many nitrogen molecules are in a balloon?
This depends on the mass of nitrogen contained in the balloon.

Describe a situation in which both vairables would increase but the relationship wouldn't be directly proportional?
Diameter and area of a circle. 2 times the diameter ==> 4 times the original area.Length and area of a rectangle. 2 times the length ==> 4 times the original area.Diameter and volume of a spherical balloon. 2 times the diameter ==> 8 times the original volume.

The balloon is 3.05 meters in diameter.

How can a line graph show you how something is expanding?
Let's say you were inflating a balloon and you measured the diameter of the balloon at the start, and then every second thereafter. You could graph the diameter of the balloon on the vertical (y) axis and the time on the horizontal (x) axis. This would show the balloon expanding over time. The slope of the line would be the rate at which the balloon would be expanding.

How do you find the diameter of a water balloon in qubic inches?
Diameter is a length measurement. Cubic inches is a volume measurement. Diameter cannot be measured in or converted to cubic inches.
