Why is the formula for the cylinder pie times radius squared times h?
There really isn't a "why"; that's just how things are. The volume of any solid with a cross-section that does not vary with height is the area of the base multiplied by the height.
What does variable acreage mean?
That means that the surface area (measured in acres, in this case) can vary.
What is the measure of how mutch surface an object has?
It's called surface area. The formulae vary depending on the shape. For example, a cube with a width of w has six sides, each of which has an area of w2, so the surface area of a cube is 6 x w2.
How do you find the volume of a floating object?
Exactly the same as for a non-floating object. Finding the volume of a shape does not vary, (i.e it's always something along the lines of height*width*depth, or area of base *height. "Table" or "surface" is irrelevant, since if it not a variable in the formula). This is true whether the object is floating or not.
What is the volume of a soccer ball?
Because the circumference can vary from 68 to 70 centimeters, the volume is approximately 5310 to 5792 cubic centimeters(324 to 353.5 cubic inches).Circumference 68 cm = Radius 34/pi = Area 5309.77 cm3Circumference 70 cm = Radius 35/pi = Area 5792.19 cm3
