It depends on many things, but if you're going by the equatorial radius as the same size, the balloon should be about 10-15% larger. Note that you can mesure the volume of irregular shapes, thanks to my good friend Archemedes ("Eurika!"). Take a mesuring container large enough to easily hold the balloon and fill it about 2/3 full. Note the volume the water occupies by the water level. Now, immerse the balloon in the water and mesure the volume by the water level again. the difference is the volume of the balloon.

Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3

-- Find the volume of a sphere with radius = 1.56 -- Find the volume of a sphere with radius = 1.61 -- The uncertainty is the difference between the bigger result and the smaller one. -- For the percent uncertainty, find out what percent that difference is of the (r = 1.56) volume. (Divide the difference of the two volumes by the volume you get with r=1.56 . Multiply the result of the division by 100, and you have the percent of uncertainty.) (Just knocking it out quickly on our calculator, we get about 9.93% uncertainty. This may or may not be correct, and you should not depend on it. But if you get the same answer, then we're probably both right.) Here's an important tool that you'll need to do this job: Volume of a sphere = 4/3 (pi) (radius)3

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.

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.

The volume of a bubble can vary depending on its size, but generally, bubbles are small spheres filled with gas. The volume of a bubble is determined by its radius and follows the formula for the volume of a sphere: V = (4/3)πr^3, where r is the radius of the bubble.

It would take approximately 0.85 cubic meters of helium to fill a 3 ft balloon.

The volume of a balloon will increase as the temperature increases between 0 degrees Celsius and 60 degrees Celsius. This is because the air inside the balloon will expand as it heats up, causing the balloon to inflate.

The volume of a sphere is the amount of space it occupies. Given a sphere's radius, r, the volume is 4/3 ∏r3

The volume will be 5723 assuming that the balloon's elasticity makes no difference.

A sphere with a radius of 7cm has a volume of 1,436.76cm3

Use the formula for a sphere. First divide the diameter by 2; that will give you the radius.
