Answer:
−9r+4r
=−9r+4r
=−r+−r+−r+−r+−r+−r+−r+−r+−r+r+r+r+r
=−r+−r+−r+−r+−r
=−5r

Answer:
The volume of the cone = 28 inch³
Step-by-step explanation:
First let's consider the formula for the volume of the shapes
For cylinder
Volume= πr²h
For cone
Volume= 1/3 πr²h
So we'd notice that no much difference except that the volume if a cylinder is divided by two to get that off a cone.
So if the volume of the cylinder is
84π inch
The volume of the cone is 84/3 = 28
The volume of the cone = 28 inch³
