What is the surface area of a spherical balloon?
And the formula for the surface area of a sphere of radius R is 4*Pi*R2.
How do you find the volume of a gas in a balloon?
Pour the water out and measure it. Empty the balloon into a large measuring cup, beaker, or something else that can measure volume. Record the amount of water that was in the balloon. The volume of water will equal the volume of gas in the other balloon.
What is the volume of a typical balloon?
| Round Latex Balloons | ||
|---|---|---|
| Balloon Size | Approximate Volume | Approximate Lift |
| 36 inches | 14.134 cu. ft. | 11.872 ounces |
| 40 inches | 19.388 cu. ft. | 1 pound .286 ounces |
| 4 feet | 33.502 cu. ft. | 1 pound 12.142 ounces |
What is the volume of this sphere?
Volume of a sphere: V = (4/3)πr.
How do you find the radius of a sphere?
How to Calculate the Radius of a Sphere?
- Radius = Diameter / 2. When the surface area is given, the formula used for the radius of a sphere is:
- Radius = ⎷[Surface Area / (4 π)] When the volume is given, the formula used for the radius of a sphere is:
- Radius = ³⎷[3 * Volume / (4 π)]
What is the volume of inflated balloon?
Method 1. Fill the balloon with water, then weigh it. The volume is then: Volume (cm^3) = Weight(gm)/1(gm/cm^3), (neglecting the weight of the empty balloon.)
How many liters of air is in a balloon?
The average volume of a hot air balloon sufficient to lift four adults is 2,200,000 liters. Typically made of nylon or dacron, a balloon envelope of this size typically weighs just 88 kg (190 lbs).
How much helium is in a balloon?
For 50 standard 9-inch latex balloons, you need around 14 cubic feet of helium. Again, for larger latex balloons you will only be able to blow up a smaller about. This amount of helium will fill around 45 10-inch latex balloons, 28 11-inch latex balloons and just 14 14-inch balloons.
What is the volume of an air balloon?
If we assume that an air balloon is a sphere, then the volume of the balloon is: where R is the radius of the balloon. The volume might be a bit bigger if it bulges on one side (near the nozzle, for example). Hot-air balloons people use to fly have shapes quite different from a sphere.
What is the rate of inflation of a spherical balloon?
Rate of inflation of a balloon. A spherical balloon is inflated at a rate of 10 cubic cm/min. At what rate is the diameter of the balloon increasing when the balloon has a diameter of 5 cm.
Is it possible to calculate the volume of a sphere?
Yes! If you know the diameter of anything that has the shape of a sphere you can calculate its volume. I am sure you know the equation is (4/3)* *r 3.
How do you fill up a 2 liter balloon?
For example, if you wanted a two liter balloon you could place the balloon into an empty two liter soft drink bottle. Of course you will have to first put a hole in the bottom of the bottle so that as you fill the balloon with air the air in the bottle can escape.
