Consider this composite figure.
Answer the following steps to find the volume of the
composite figure.
What is the volume of the 3 mm-tall cone?
V= _ pi mm^3

What is the volume of the cylinder?
V = ___ pi mm^3

What is the volume of the 1 mm-tall cone?
V = _ pi mm^3

What is the volume of the composite figure?

V=_ pi mm^3

Given:

Height of top cone = 3 mm

Radius = 2 mm

Height of cylinder = 4 mm

Height of bottom cone = 1 mm

To find:

The volume of the composite figure

Solution:

Volume of 3 mm tall cone

Volume of 3 mm tall  cone = 4π mm³

Volume of cylinder =

Volume of cylinder = 16π mm³

Volume of 1 mm tall cone

Volume of 1 mm tall  cone = 1.33π mm³

Volume of composite figure = 4π + 16π + 1.33π

                                                = 21.33π mm³

The volume of the composite figure is 21.33π mm³.
