The area of the circle segment can be found using its height and the radius of the circle. If you know a cylinders height and lateral area but not its radius. For any cylinder with base radius r and height h the volume will be base times the height.
Because a cylinder is a flat-top figure a solid with two congruent parallel bases the base can be either the top or bottom.
In Excel p is represented in a formula with the PI function which returns the number 314159265358979 accurate to 15 digits. Recall that the formula to get the volume of cylinders is pi r 2 h with pi 3141592653589793 Therefore the volume depends on the size of r and h. The area of the circle segment can be found using its height and the radius of the circle. R squared times pi times height 12 times 12 times pi times 20 144 times pi times 20 which is around 9048 meters squared.
