Virtual Nerd: How Do You Find the Lateral and Surface Areas of a Cylinder?

The measurements are all in the can. The review for the math portion of the General Certificate of Secondary Education assessments provides scholars the opportunity to review finding volume and surface area of a cylinder. Pupils work on...

Did you know you can use the Pythagorean theorem to find the slant height of a cone? You can! Just watch this tutorial and see how you can find the lateral and surface area of a given cone using slant height and the Pythagorean theorem.

The lateral surface area of a cone. Hmmm, what does that mean? Oh, it means the part you see if the cone was sitting on a flat surface, so it does not include the base. But if you want to include the base then it would be finding the...

Take a look at this tutorial to see how to apply each formula to the given information to find the lateral area and surface area of a cone. [4:51]

There are three formulas that need to be used to solve this problem. The formula for the lateral area of a cylinder, the formula for the circular base of the cylinder, and then the formula for the surface area. It seems like quite a bit,...

What are lateral faces? How do you find the area of all the lateral faces? What to do with the perimeter of the base? Then what do you do with those values? You use it to help determine the total lateral area of a rectangle. Yes, more...

A regular pyramid has four equal triangular shaped sides and a square base. The lateral area is comprised of the area of the four triangular sides. The surface area is the area of the four triangular sides plus the area of the base....

There are several pieces to this problem. But luckily all the necessary pieces are here. There are five variables and three different formulas to use to get the solutions. The instructor diagrams the triangular prism and labels the...

Probability is the likelihood that a given event will take place. So how do you determine the probability of a simple event? Watch this example using marbles for an explanation. [4:36]

In this tutorial, you'll see how to apply each formula to the given information to find the lateral area and surface area of a regular pyramid. [5:18]
