Volume of a Cylinder
Volume of a cylinder is a Grade 7 geometry concept in Big Ideas Math Advanced 2, Chapter 8: Volume and Similar Solids. The volume formula is V equals pi times r squared times h, where r is the radius of the circular base and h is the height. For example, a cylindrical can with radius 5 cm and height 10 cm has a volume of 250 pi, approximately 785.4 cubic centimeters.
Key Concepts
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.

Common Questions
What is the formula for the volume of a cylinder?
V equals pi times r squared times h, where r is the base radius and h is the height. This multiplies the circular base area by the height.
How do you calculate the volume of a cylindrical can?
Identify the radius and height, substitute into V equals pi r squared h. For a can with radius 3 inches and height 6 inches, V equals pi times 9 times 6 equals 54 pi cubic inches.
What units are used for cylinder volume?
Volume is always measured in cubic units such as cubic centimeters, cubic inches, or cubic feet, because it measures three-dimensional space.
What textbook covers cylinder volume in Grade 7?
Big Ideas Math Advanced 2, Chapter 8: Volume and Similar Solids covers the cylinder volume formula and its applications.
