Finding Missing Dimensions of Cylinders

This tutorial teaches how to find missing dimensions of a cylinder when given the volume and one other dimension, such as radius, height, diameter, or circumference. It covers the use of formulas, substitution of values, and solving equations for unknown variables. The video includes practice problems, advanced problem-solving techniques, and emphasizes the importance of using the correct formula and calculator operations. The tutorial concludes with a summary and additional practice questions.

What formula is used to calculate the volume of a cylinder?

• V = pi * r^2 * h

• V = pi * d^2 * h

• V = 2 * pi * r * h

• V = pi * r * h
