Jordan,+Kyle+&+Marcus+-+Geometry

This is our geometry page. For geometry, we are doing cylinders, the net and the volume of a cylinder. The net of a cylinder is as shown.

The circumference of the circle is the length of the side the circle is touching. To find circumference, you must know the formula. The formula is Pi times the diameter of the circle. Know that you know that, you can find the area of the rectangle. The problems usually will give you that one side. Once you figure that out, you can find the area of the circles. The formula is Pi r squared. To find the total surface area, you have to add up the area of the rectangle and the two circles.

To find the volume is quit simple. It is simply the are of the circle times the height. Or Pi radius squared time height. The cylinder looks like this. Wow!!!!
