Cylinder volume & surface area - Khan Academy
A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r². Learn how to use these formulas to solve an example problem. Created by Sal Khan.
Applying volume of solids (video) | Khan Academy
Calculate the volume of a grain hopper and then use the given rate to solve an applied problem.
Volume with cross sections: semicircle (video) | Khan Academy
The volume to calculate the volume of a cone is (pi*r^2*h)/3. To get half a cone, I divided that by 2, giving me the formula ((pi*r^2*h)/3)/2. From here on, I only need to substitute in the values for r and h to get the correct answer.
