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).
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.
How wide is a 31 inch balloon?
A 31-inch balloon would have a diameter of 31 inches when fully inflated. This means the width of the balloon, from one side to the other, would be approximately 31 inches.
What is balloon algae?
Balloon algae, also known as green balloon algae, is a type of algae that forms large, spherical, greenish bubbles that can float freely in the water. It is often found in freshwater aquariums and ponds, and can be challenging to control as it can quickly reproduce and spread. Balloon algae can outcompete other aquatic plants for nutrients, leading to imbalances in the ecosystem.
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 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.
What is the perimeter of a hot air balloon?
The perimeter of a hot air balloon is the sum of the lengths of all its sides. Typically, hot air balloons do not have a traditional perimeter measurement as they are not geometric shapes with straight sides like squares or circles.
The volume of air in a balloon?
The volume of air in a balloon can be calculated by measuring the dimensions of the balloon and using the formula for the volume of a sphere (4/3 x pi x r^3) if the balloon is spherical. If the balloon is not spherical, the volume can be estimated by using the formula for the volume of a cylinder (pi x r^2 x h) or a different geometric shape that closely approximates the balloon's shape.
10 feet dia balloon how many meters?
The balloon is 3.05 meters in diameter.
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.

What is the size of a barrage balloon?
A barrage balloon typically has a diameter of around 55 feet and a length of about 72 feet.
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 creates pressure inside of a balloon?
The pressure inside a balloon is created by the air molecules contained within the balloon pushing against the walls of the balloon. As more air is blown into the balloon, the number of air molecules increases, leading to a higher pressure inside the balloon.
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 Can you find the volume of an inflated balloon?
To find the volume of an inflated balloon, you can measure its diameter using a ruler and then use the formula for the volume of a sphere, V = (4/3) * pi * r^3, where r is the radius (half of the diameter) of the balloon. Plug in the radius and calculate the volume. Alternatively, you can submerge the inflated balloon in a container of water and measure the water displacement to find the volume of the balloon.
Did the Montgolfier Brothers fly the first hot air balloon?
Yes, the Montgolfier Brothers, Joseph-Michel and Jacques-Étienne, are credited with launching the first manned hot air balloon flight on June 4, 1783. A sheep, a duck, and a rooster were the first living passengers.
