Composite figures

Question

I’m struggling on volume and composite figures and I need the answers

Answer 1

You don't need answers--you need to LEARN THE METHODS BY WHICH ANSWERS ARE COMPUTED.

That is the purpose of the textbook, and of your teacher and his lectures.

 

Some composite figures consist of pieces that are recognizable, e.g. semicircles surmounting a rectangle, or a cone atop a cylinder, or a pyramid surmounting a cube.  For each of these entities, there are volume (or area) formulas, by which to calculate individual parts of an overall volume or area.

 

You need to develop superior study habits, such as making flash cards showing diagrams and associated formulas, and also the ability to read explanation in math books.
