You mean the surface area, right? Assuming the balloon is approximately spherical, you can measure the diameter, divide by two to get the radius & plug that into this formula.
A=¾πr²
Where A is the area, r is the radius and π is the ratio of the circumpherence to the radius of a circle. 3.14 or 22/7 are good approximations to π, also a decent calculator will have a better approximation built in. To look it up search for "pi" (that's the Greek letter's name).
Area(air) = 2
-- Find out the population of the area. -- Find out the area of the area. -- Divide the population by the area. The result is the population density of the area.
this is funny cause i took an online test with this question
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
To find the area of 3ft by 1ft, you multiply the two. So the area is 3 square feet.
One can find and book hot air balloon rides in Niagara on the 'Balloon Over Letchworth' website. One can also find such balloon rides listed on 'Trip Advisor'.
You do not need to find balloon boy and you can't find him
Blowing up a balloon is not an example of diffusion. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while blowing up a balloon involves forcing air into the balloon using pressure.
Popping a balloon with a pin requires less force because the pin concentrates the pressure to a small area, piercing the balloon easily. Stepping on a balloon distributes your weight across a larger area, making it harder to apply enough force to pop the balloon.
In a high pressure area, the hot air balloon will tend to float lower as the surrounding air is denser and exerts more pressure on the balloon. This can cause the balloon to descend unless the pilot adjusts the temperature of the air inside the balloon to maintain altitude.
www.balloons4you.com is an excellent choice for all your balloon needs. They offer balloon decorations, balloon sculptures, and custom balloon decorations among other things.
Find your balloon
This answer would be different in every area. I would look up companies in your area (or the area you will be traveling) for a place to do a hot air balloon ride and call them and find out. Make sure you specify the ages of the people in your family as it might change from children to adults. From the research I did I found it could be around $190.00. I found a website that has info on worldwide rides http://www.hotairballooning.com/balloon-rides/
When you squeeze a balloon, the pressure inside the balloon is increased the most in the area where you are applying the squeezing force. This is because the force you exert causes the air molecules in that area to be compressed, resulting in an increase in pressure.
The pressure inside the balloon is calculated by dividing the force by the area. In this case, 1.5 N / 0.5 m^2 = 3 Pa (Pascals). Therefore, the pressure inside the balloon is 3 Pascals.

The change in the area would increase by a factor of 4. When the diameter doubles, the radius also doubles. Since the formula for the surface area of a sphere is 4πr^2, when the radius doubles, the area increases by a factor of 4.
