Section 1
Volume of a Cylinder
Property
Volume is the amount of space contained within a three-dimensional object. It is measured in cubic units, such as cubic feet or cubic centimeters.
Cylinder Volume Formula:
In this Grade 8 lesson from Reveal Math, Course 3 (Module 10), students learn how to calculate the volume of a cylinder using the formula V = πr²h, applying it to problems where either the radius or diameter is given. Students practice expressing volume in terms of π as an exact answer and as a decimal approximation rounded to the nearest tenth. The lesson also extends to multi-step real-world problems, such as finding the weight of a cylindrical object by multiplying its calculated volume by a given unit weight.

Section 2
The Height and Volume of Cylinders
A cylinder is a solid figure with two parallel circular bases of the same size. For a cylinder with radius and height :
Volume: or (where is the area of the base)
Section 3
Area of circles
For a circle with radius :
The area is .
The number (pi) is a constant used for all circles. For exact answers, leave the symbol in the solution. For approximate answers, use or .
