What is a Cylinder?

• Central part of a reciprocating engine or pump, and space in which a piston travels.

• Symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares.

• A solid geometric figure with straight parallel sides and a circular, or oval, cross section.

What is the formula for a cone figure?

• V = ⅓π²rh

• V = ⅓πr²h

• V = l × w × h

What is the formula for a Sphere figure?

• V = ⅓πr³

• V = ⅓πr²h

• V = ⁴/₃πr³

What is a geometric net?

•  net is the shape that is formed by unfolding a three-dimensional figure. In other words, a net is composed of all of the faces of the figure.

• Free from all charges or deductions: such asa : remaining after the deduction of all charges, outlay, or loss

• They are devices made from fibers woven in a grid-like structure, and are usually meshes formed by knotting a relatively thin thread.
