How do you calculate the volume of an irregular object?
i made this model of a hot air balloon. i know the perimeter of each shape i used because i carefully drafted the shapes i used. but i want to know how i can calculate the volume, so i can find out how much air it can hold. i want to know if there is a certain formula that you use. thanks and honest answers plz!!!!!!!!!!!!!!!!!!!!!!!
It would be possible to calculate it, but it requires integral calculus.
Here's the basic procedure: imagine you sliced the balloon horizontally into a lot of pieces. Those pieces would have a circumference equal to the width of the pieces at that point, multiplied by the number of pieces that make up the balloon. If you calculate the upper and lower circumferences, you can calculate conic sections that approximate the curved shape of the balloon. By adding up all of those conical approximations, you can get an approximation of the volume of the balloon. The more cones you calculate, the more accurate that approximation will be.
