Finding Dimensions of a Cylinder from Volume

The video tutorial explains how to find the dimensions of a cylinder, specifically the height and radius, using given information such as volume and diameter. It begins with an introduction to the formula for the volume of a cylinder and demonstrates how to solve for the height when the volume and diameter are known. The tutorial then covers solving for the radius when the volume and height are provided, using mathematical operations like division and square roots. The video concludes with a brief mention of an assignment related to the topic.

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

• V = πr(h^2)

• V = πr^2h

• V = 2πrh

• V = πr^2 + h
