8th Grade Math
22. 8.G.C.9
22.4 Volume of cylinders
Volume of cylinders
What You'll Learn
Calculate the volume of a cylinder using the formula V = πr²h
Identify the radius, diameter, and height from cylinder diagrams and nets
Convert between diameter and radius to solve volume problems
Apply the cylinder volume formula to solve for missing dimensions
Compare volumes of different cylinders to determine which is larger
What You'll Practice
1
Finding volume from cylinder nets with given radius and height
2
Calculating volume when diameter is given instead of radius
3
Comparing volumes of two cylinders with different dimensions
4
Solving for the length of a cylinder given its volume and diameter
Why This Matters
Understanding cylinder volume is essential for real-world applications like calculating water pipe capacity, storage tank sizes, and container volumes. You'll use this skill in physics, engineering, and everyday problem-solving involving cylindrical objects.
