Unpacked Content

Knowledge

Students know:

the volume formulas for cylinders, cones, and spheres.
That 3.14 is an approximation of pi commonly used in these volume formulas.
That composite three dimensional objects in the real-world can be created by combining cylinders, cones, and spheres in part or whole.

Skills

Students are able to:

calculate the volume of cones, cylinders, and spheres given in real-world contexts. often times approximating solutions to a specified decimal place.
